An Oblivious Pseudorandom Function (OPRF) is a two-party protocol between client and server for computing the output of a Pseudorandom Function (PRF). The server provides the PRF secret key, and the client provides the PRF input. At the end of the protocol, the client learns the PRF output without learning anything about the PRF secret key, and the server learns neither the PRF input nor output. An OPRF can also satisfy a notion of 'verifiability', called a VOPRF. A VOPRF ensures clients can verify that the server used a specific private key during the execution of the protocol. A VOPRF can also be partially-oblivious, called a POPRF. A POPRF allows clients and servers to provide public input to the PRF computation. This document specifies an OPRF, VOPRF, and POPRF instantiated within standard prime-order groups, including elliptic curves. This document is a product of the Crypto Forum Research Group (CFRG) in the IRTF.¶

A Pseudorandom Function (PRF) F(k, x) is an efficiently computable function taking a private key k and a value x as input. This function is pseudorandom if the keyed function K(_) = F(k, _) is indistinguishable from a randomly sampled function acting on the same domain and range as K(). An Oblivious PRF (OPRF) is a two-party protocol between a server and a client, where the server holds a PRF key k and the client holds some input x. The protocol allows both parties to cooperate in computing F(k, x) such that the client learns F(k, x) without learning anything about k; and the server does not learn anything about x or F(k, x). A Verifiable OPRF (VOPRF) is an OPRF wherein the server also proves to the client that F(k, x) was produced by the key k corresponding to the server's public key the client knows. A Partially-Oblivious PRF (POPRF) is a variant of a VOPRF wherein client and server interact in computing F(k, x, y), for some PRF F with server-provided key k, client-provided input x, and public input y, and client receives proof that F(k, x, y) was computed using k corresponding to the public key that the client knows. A POPRF with fixed input y is functionally equivalent to a VOPRF.¶
OPRFs have a variety of applications, including: password-protected secret sharing schemes [JKKX16], privacy-preserving password stores [SJKS17], and password-authenticated key exchange or PAKE [I-D.irtf-cfrg-opaque]. Verifiable OPRFs are necessary in some applications such as Privacy Pass [I-D.ietf-privacypass-protocol]. Verifiable OPRFs have also been used for password-protected secret sharing schemes such as that of [JKK14].¶
This document specifies OPRF, VOPRF, and POPRF protocols built upon prime-order groups. The document describes each protocol variant, along with application considerations, and their security properties.¶
This document represents the consensus of the Crypto Forum Research Group (CFRG).¶
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.¶
The following functions and notation are used throughout the document.¶
x, we write len(x) to denote its length in bytes.¶
x and y, write x || y to denote their
concatenation.¶
x into a byte array
of specified length xLen as described in [RFC8017]. Note that
this function returns a byte array in big-endian byte order.¶
T U[N] refers to an array called U containing N items of type
T. The type opaque means one single byte of uninterpreted data. Items of
the array are zero-indexed and referred as U[j] such that 0 <= j < N.¶
All algorithms and procedures described in this document are laid out in a Python-like pseudocode. Each function takes a set of inputs and parameters and produces a set of output values. Parameters become constant values once the protocol variant and the ciphersuite are fixed.¶
The PrivateInput data type refers to inputs that are known only to the client
in the protocol, whereas the PublicInput data type refers to inputs that are
known to both client and server in the protocol. Both PrivateInput and
PublicInput are opaque byte strings of arbitrary length no larger than 2^13 octets.¶
String values such as "DeriveKeyPair", "Seed-", and "Finalize" are ASCII string literals.¶
The following terms are used throughout this document.¶
The protocols in this document have two primary dependencies:¶
Group: A prime-order group implementing the API described below in Section 2.1.
See Section 4 for specific instances of groups.¶
Hash: A cryptographic hash function whose output length is Nh bytes.¶
Section 4 specifies ciphersuites as combinations of Group and Hash.¶
In this document, we assume the construction of an additive, prime-order
group Group for performing all mathematical operations. In prime-order groups,
any element (other than the identity) can generate the other elements of the
group. Usually, one element
is fixed and defined as the group generator. Such groups are
uniquely determined by the choice of the prime p that defines the
order of the group. (There may, however, exist different representations
of the group for a single p. Section 4 lists specific groups which
indicate both order and representation.)¶
The fundamental group operation is addition + with identity element
I. For any elements A and B of the group, A + B = B + A is
also a member of the group. Also, for any A in the group, there exists an element
-A such that A + (-A) = (-A) + A = I. Scalar multiplication by r is
equivalent to the repeated application of the group operation on an
element A with itself r-1 times, this is denoted as r*A = A + ... + A.
For any element A, p*A=I. The case when the scalar multiplication is
performed on the group generator is denoted as ScalarMultGen(r).
Given two elements A and B, the discrete logarithm problem is to find
an integer k such that B = k*A. Thus, k is the discrete logarithm of
B with respect to the base A.
The set of scalars corresponds to GF(p), a prime field of order p, and are
represented as the set of integers defined by {0, 1, ..., p-1}.
This document uses types
Element and Scalar to denote elements of the group and its set of
scalars, respectively.¶
We now detail a number of member functions that can be invoked on a prime-order group.¶

This function can raise a DeserializeError if deserialization fails; see
Section 4 for group-specific input validation steps.¶
Section 4 contains details for the implementation of this interface for different prime-order groups instantiated over elliptic curves. In particular, for some choices of elliptic curves, e.g., those detailed in [RFC7748], which require accounting for cofactors, Section 4 describes required steps necessary to ensure the resulting group is of prime order.¶
A proof of knowledge allows a prover to convince a verifier that some statement is true. If the prover can generate a proof without interaction with the verifier, the proof is noninteractive. If the verifier learns nothing other than whether the statement claimed by the prover is true or false, the proof is zero-knowledge.¶
This section describes a noninteractive zero-knowledge proof for discrete logarithm equivalence (DLEQ), which is used in the construction of VOPRF and POPRF. A DLEQ proof demonstrates that two pairs of group elements have the same discrete logarithm without revealing the discrete logarithm.¶
The DLEQ proof resembles the Chaum-Pedersen [ChaumPedersen] proof, which is shown to be zero-knowledge by Jarecki, et al. [JKK14] and is noninteractive after applying the Fiat-Shamir transform [FS00]. Furthermore, Davidson, et al. [DGSTV18] showed a proof system for batching DLEQ proofs that has constant-size proofs with respect to the number of inputs. The specific DLEQ proof system presented below follows this latter construction with two modifications: (1) the transcript used to generate the seed includes more context information, and (2) the individual challenges for each element in the proof is derived from a seed-prefixed hash-to-scalar invocation rather than being sampled from a seeded PRNG. The description is split into two sub-sections: one for generating the proof, which is done by servers in the verifiable protocols, and another for verifying the proof, which is done by clients in the protocol.¶
Generating a proof is done with the GenerateProof function, defined below.
Given elements A and B, two non-empty lists of elements C and D of length
m, and a scalar k; this function produces a proof that k*A == B
and k*C[i] == D[i] for each i in [0, ..., m - 1].
The output is a value of type Proof, which is a tuple of two Scalar
values.¶
GenerateProof accepts lists of inputs to amortize the cost of proof
generation. Applications can take advantage of this functionality to
produce a single, constant-sized proof for m DLEQ inputs, rather
than m proofs for m DLEQ inputs.¶

Scalar k

When used in the protocol described in Section 3, the parameter contextString is
as defined in Section 3.2.¶
Verifying a proof is done with the VerifyProof function, defined below.
This function takes elements A and B, two non-empty lists of elements C and D
of length m, and a Proof value output from GenerateProof. It outputs a
single boolean value indicating whether or not the proof is valid for the
given DLEQ inputs. Note this function can verify proofs on lists of inputs
whenever the proof was generated as a batched DLEQ proof with the same inputs.¶

When used in the protocol described in Section 3, the parameter contextString is
as defined in Section 3.2.¶
In this section, we define three protocol variants referred to as the OPRF, VOPRF, and POPRF modes with the following properties.¶
In the OPRF mode, a client and server interact to compute output = F(skS, input),
where input is the client's private input, skS is the server's private key,
and output is the OPRF output. After the execution of the protocol, the
client learns output and the server learns nothing.
This interaction is shown below.¶
Client Server(skS)
-------------------------------------------------------------------
blind, blindedElement = Blind(input)
blindedElement
---------->
evaluatedElement = BlindEvaluate(skS, blindedElement)
evaluatedElement
<----------
output = Finalize(input, blind, evaluatedElement)
In the VOPRF mode, the client additionally receives proof that the server used
skS in computing the function. To achieve verifiability, as in [JKK14], the
server provides a zero-knowledge proof that the key provided as input by the server in
the BlindEvaluate function is the same key as it used to produce the server's public key, pkS,
which the client receives as input to the protocol. This proof does not reveal the server's
private key to the client. This interaction is shown below.¶
Client(pkS) <---- pkS ------ Server(skS, pkS)
-------------------------------------------------------------------
blind, blindedElement = Blind(input)
blindedElement
---------->
evaluatedElement, proof = BlindEvaluate(skS, pkS,
blindedElement)
evaluatedElement, proof
<----------
output = Finalize(input, blind, evaluatedElement,
blindedElement, pkS, proof)
The POPRF mode extends the VOPRF mode such that the client and
server can additionally provide a public input info that is used in computing
the pseudorandom function. That is, the client and server interact to compute
output = F(skS, input, info) as is shown below.¶
Client(pkS, info) <---- pkS ------ Server(skS, pkS, info)
-------------------------------------------------------------------
blind, blindedElement, tweakedKey = Blind(input, info, pkS)
blindedElement
---------->
evaluatedElement, proof = BlindEvaluate(skS, blindedElement,
info)
evaluatedElement, proof
<----------
output = Finalize(input, blind, evaluatedElement,
blindedElement, proof, info, tweakedKey)
Each protocol consists of an offline setup phase and an online phase, described in Section 3.2 and Section 3.3, respectively. Configuration details for the offline phase are described in Section 3.1.¶
Each of the three protocol variants are identified with a one-byte value (in hexadecimal):¶
| Mode | Value |
|---|---|
| modeOPRF | 0x00 |
| modeVOPRF | 0x01 |
| modePOPRF | 0x02 |
Additionally, each protocol variant is instantiated with a ciphersuite,
or suite. Each ciphersuite is identified with a two-byte value, referred
to as suiteID; see Section 4 for the registry of initial values.¶
The mode and ciphersuite ID values are combined to create a "context string" used throughout the protocol with the following function:¶
def CreateContextString(mode, suiteID): return "VOPRF10-" || I2OSP(mode, 1) || I2OSP(suiteID, 2)¶
[[RFC editor: please change "VOPRF10" to "RFCXXXX", where XXXX is the final number, here and elsewhere before publication.]]¶
In the offline setup phase, the server key pair (skS, pkS) is generated
using the following GenerateKeyPair function, which produces a randomly
generate private and public key pair. Section 3.2.1 lists a
deterministic key generation function DeriveKeyPair that can be used
to implement GenerateKeyPair as DeriveKeyPair(random(Ns), info), with
optional (possibly empty) application-chosen public info string.¶
Input: None Output: Scalar skS Element pkS Parameters: Group G def GenerateKeyPair(): skS = G.RandomScalar() pkS = G.ScalarMultGen(skS) return skS, pkS¶
Also during the offline setup phase, both the client and server create a
context used for executing the online phase of the protocol after agreeing on a
mode and ciphersuite value suiteID. The context, such as OPRFServerContext,
is an implementation-specific data structure that stores a context string and
the relevant key material for each party.¶
The OPRF variant server and client contexts are created as follows:¶
def SetupOPRFServer(suiteID, skS): contextString = CreateContextString(modeOPRF, suiteID) return OPRFServerContext(contextString, skS) def SetupOPRFClient(suiteID): contextString = CreateContextString(modeOPRF, suiteID) return OPRFClientContext(contextString)¶
The VOPRF variant server and client contexts are created as follows:¶
def SetupVOPRFServer(suiteID, skS, pkS): contextString = CreateContextString(modeVOPRF, suiteID) return VOPRFServerContext(contextString, skS) def SetupVOPRFClient(suiteID, pkS): contextString = CreateContextString(modeVOPRF, suiteID) return VOPRFClientContext(contextString, pkS)¶
The POPRF variant server and client contexts are created as follows:¶
def SetupPOPRFServer(suiteID, skS, pkS): contextString = CreateContextString(modePOPRF, suiteID) return POPRFServerContext(contextString, skS) def SetupPOPRFClient(suiteID, pkS): contextString = CreateContextString(modePOPRF, suiteID) return POPRFClientContext(contextString, pkS)¶
This section describes a deterministic key generation function, DeriveKeyPair.
It accepts a randomly generated seed of length
Ns bytes and an optional (possibly empty) public info string. The
constant Ns corresponds to the size in bytes of a serialized Scalar and is
defined in Section 2.1.¶
Input:
opaque seed[Ns]
PublicInput info
Output:
Scalar skS
Element pkS
Parameters:
Group G
PublicInput contextString
Errors: DeriveKeyPairError
def DeriveKeyPair(seed, info):
deriveInput = seed || I2OSP(len(info), 2) || info
counter = 0
skS = 0
while skS == 0:
if counter > 255:
raise DeriveKeyPairError
skS = G.HashToScalar(deriveInput || I2OSP(counter, 1),
DST = "DeriveKeyPair" || contextString)
counter = counter + 1
pkS = G.ScalarMultGen(skS)
return skS, pkS
¶
In the online phase, the client and server engage in a two message protocol to compute the protocol output. This section describes the protocol details for each protocol variant. Throughout each description the following parameters are assumed to exist:¶
Applications serialize protocol messages between client and server for
transmission. Elements and scalars are serialized to byte arrays, and values
of type Proof are serialized as the concatenation of two serialized scalars.
Deserializing these values can fail, in which case the application MUST abort
the protocol raising a DeserializeError failure.¶
Applications MUST check that input Element values received over the wire are not the group identity element. This check is handled after deserializing Element values; see Section 4 for more information and requirements on input validation for each ciphersuite.¶
The OPRF protocol begins with the client blinding its input, as described
by the Blind function below. Note that this function can fail with an
InvalidInputError error for certain inputs that map to the group identity
element. Dealing with this failure is an application-specific decision;
see Section 5.3.¶
Input:
PrivateInput input
Output:
Scalar blind
Element blindedElement
Parameters:
Group G
Errors: InvalidInputError
def Blind(input):
blind = G.RandomScalar()
inputElement = G.HashToGroup(input)
if inputElement == G.Identity():
raise InvalidInputError
blindedElement = blind * inputElement
return blind, blindedElement
¶
Clients store blind locally, and send blindedElement to the server for evaluation.
Upon receipt, servers process blindedElement using the BlindEvaluate function described
below.¶
Input: Scalar skS Element blindedElement Output: Element evaluatedElement def BlindEvaluate(skS, blindedElement): evaluatedElement = skS * blindedElement return evaluatedElement¶
Servers send the output evaluatedElement to clients for processing.
Recall that servers may process multiple client inputs by applying the
BlindEvaluate function to each blindedElement received, and returning an
array with the corresponding evaluatedElement values.¶
Upon receipt of evaluatedElement, clients process it to complete the
OPRF evaluation with the Finalize function described below.¶
Input:
PrivateInput input
Scalar blind
Element evaluatedElement
Output:
opaque output[Nh]
Parameters:
Group G
def Finalize(input, blind, evaluatedElement):
N = G.ScalarInverse(blind) * evaluatedElement
unblindedElement = G.SerializeElement(N)
hashInput = I2OSP(len(input), 2) || input ||
I2OSP(len(unblindedElement), 2) || unblindedElement ||
"Finalize"
return Hash(hashInput)
¶
An entity which knows both the secret key and the input can compute the PRF
result using the following Evaluate function.¶
Input:
Scalar skS
PrivateInput input
Output:
opaque output[Nh]
Parameters:
Group G
Errors: InvalidInputError
def Evaluate(skS, input):
inputElement = G.HashToGroup(input)
if inputElement == G.Identity():
raise InvalidInputError
evaluatedElement = skS * inputElement
issuedElement = G.SerializeElement(evaluatedElement)
hashInput = I2OSP(len(input), 2) || input ||
I2OSP(len(issuedElement), 2) || issuedElement ||
"Finalize"
return Hash(hashInput)
¶
The VOPRF protocol begins with the client blinding its input, using the same
Blind function as in Section 3.3.1. Clients store the output blind locally
and send blindedElement to the server for evaluation. Upon receipt,
servers process blindedElement to compute an evaluated element and DLEQ
proof using the following BlindEvaluate function.¶
Input:
Scalar skS
Element pkS
Element blindedElement
Output:
Element evaluatedElement
Proof proof
Parameters:
Group G
def BlindEvaluate(skS, pkS, blindedElement):
evaluatedElement = skS * blindedElement
blindedElements = [blindedElement] // list of length 1
evaluatedElements = [evaluatedElement] // list of length 1
proof = GenerateProof(skS, G.Generator(), pkS,
blindedElements, evaluatedElements)
return evaluatedElement, proof
¶
In the description above, inputs to GenerateProof are one-item
lists. Using larger lists allows servers to batch the evaluation of multiple
elements while producing a single batched DLEQ proof for them.¶
The server sends both evaluatedElement and proof back to the client.
Upon receipt, the client processes both values to complete the VOPRF computation
using the Finalize function below.¶
Input:
PrivateInput input
Scalar blind
Element evaluatedElement
Element blindedElement
Element pkS
Proof proof
Output:
opaque output[Nh]
Parameters:
Group G
Errors: VerifyError
def Finalize(input, blind, evaluatedElement,
blindedElement, pkS, proof):
blindedElements = [blindedElement] // list of length 1
evaluatedElements = [evaluatedElement] // list of length 1
if VerifyProof(G.Generator(), pkS, blindedElements,
evaluatedElements, proof) == false:
raise VerifyError
N = G.ScalarInverse(blind) * evaluatedElement
unblindedElement = G.SerializeElement(N)
hashInput = I2OSP(len(input), 2) || input ||
I2OSP(len(unblindedElement), 2) || unblindedElement ||
"Finalize"
return Hash(hashInput)
¶
As in BlindEvaluate, inputs to VerifyProof are one-item lists. Clients can
verify multiple inputs at once whenever the server produced a batched DLEQ proof
for them.¶
Finally, an entity which knows both the secret key and the input can compute the PRF
result using the Evaluate function described in Section 3.3.1.¶
The POPRF protocol begins with the client blinding its input, using the
following modified Blind function. In this step, the client also binds a
public info value, which produces an additional tweakedKey to be used later
in the protocol. Note that this function can fail with an
InvalidInputError error for certain private inputs that map to the group
identity element, as well as certain public inputs that, if not detected at
this point, will cause server evaluation to fail. Dealing with either failure
is an application-specific decision; see Section 5.3.¶
Input:
PrivateInput input
PublicInput info
Element pkS
Output:
Scalar blind
Element blindedElement
Element tweakedKey
Parameters:
Group G
Errors: InvalidInputError
def Blind(input, info, pkS):
framedInfo = "Info" || I2OSP(len(info), 2) || info
m = G.HashToScalar(framedInfo)
T = G.ScalarMultGen(m)
tweakedKey = T + pkS
if tweakedKey == G.Identity():
raise InvalidInputError
blind = G.RandomScalar()
inputElement = G.HashToGroup(input)
if inputElement == G.Identity():
raise InvalidInputError
blindedElement = blind * inputElement
return blind, blindedElement, tweakedKey
¶
Clients store the outputs blind and tweakedKey locally and send blindedElement to
the server for evaluation. Upon receipt, servers process blindedElement to
compute an evaluated element and DLEQ proof using the following BlindEvaluate function.¶
Input:
Scalar skS
Element blindedElement
PublicInput info
Output:
Element evaluatedElement
Proof proof
Parameters:
Group G
Errors: InverseError
def BlindEvaluate(skS, blindedElement, info):
framedInfo = "Info" || I2OSP(len(info), 2) || info
m = G.HashToScalar(framedInfo)
t = skS + m
if t == 0:
raise InverseError
evaluatedElement = G.ScalarInverse(t) * blindedElement
tweakedKey = G.ScalarMultGen(t)
evaluatedElements = [evaluatedElement] // list of length 1
blindedElements = [blindedElement] // list of length 1
proof = GenerateProof(t, G.Generator(), tweakedKey,
evaluatedElements, blindedElements)
return evaluatedElement, proof
¶
In the description above, inputs to GenerateProof are one-item
lists. Using larger lists allows servers to batch the evaluation of multiple
elements while producing a single batched DLEQ proof for them.¶
BlindEvaluate triggers InverseError when the function is about to
calculate the inverse of a zero scalar, which does not exist and therefore
yields a failure in the protocol.
This only occurs for info values that map to the secret key of the server. Thus,
clients that observe this signal are assumed to know the server secret key. Hence,
this error can be a signal for the server to replace its secret key.¶
The server sends both evaluatedElement and proof back to the client.

A ciphersuite (also referred to as 'suite' in this document) for the protocol wraps the functionality required for the protocol to take place. The ciphersuite should be available to both the client and server, and agreement on the specific instantiation is assumed throughout.¶
A ciphersuite contains instantiations of the following functionalities:¶
Group: A prime-order Group exposing the API detailed in Section 2.1, with the
generator element defined in the corresponding reference for each group. Each
group also specifies HashToGroup, HashToScalar, and serialization
functionalities. For
HashToGroup, the domain separation tag (DST) is constructed in accordance
with the recommendations in [I-D.irtf-cfrg-hash-to-curve], Section 3.1.
For HashToScalar, each group specifies an integer order that is used in
reducing integer values to a member of the corresponding scalar field.¶
Hash: A cryptographic hash function whose output length is Nh bytes long.¶
This section specifies an initial registry of ciphersuites with supported groups and hash functions. It also includes implementation details for each ciphersuite, focusing on input validation, as well as requirements for future ciphersuites.¶
For each ciphersuite, contextString is that which is computed in the Setup functions. Applications should take caution in using ciphersuites targeting P-256 and ristretto255. See Section 7.2 for related discussion.¶
Group: ristretto255 [RISTRETTO]¶

A critical requirement of implementing the prime-order group using
elliptic curves is a method to instantiate the function
HashToGroup, that maps inputs to group elements. In the elliptic
curve setting, this deterministically maps inputs (as byte arrays) to
uniformly chosen points on the curve.¶
In the security proof of the construction Hash is modeled as a random
oracle. This implies that any instantiation of HashToGroup must be
pre-image and collision resistant. In Section 4 we give
instantiations of this functionality based on the functions described in
[I-D.irtf-cfrg-hash-to-curve]. Consequently, any OPRF implementation
must adhere to the implementation and security considerations discussed
in [I-D.irtf-cfrg-hash-to-curve] when instantiating the function.¶
The DeserializeElement and DeserializeScalar functions instantiated for a particular prime-order group corresponding to a ciphersuite MUST adhere to the description in Section 2.1. Future ciphersuites MUST describe how input validation is done for DeserializeElement and DeserializeScalar.¶
Additionally, future ciphersuites must take care when choosing the security level of the group. See Section 7.2.3 for additional details.¶
Two popular algorithms for generating a random integer uniformly distributed in the range [0, G.Order() -1] are as follows:¶
Generate a random byte array with Ns bytes, and attempt to map to a Scalar
by calling DeserializeScalar in constant time. If it succeeds, return the
result. If it fails, try again with another random byte array, until the
procedure succeeds. Failure to implement DeserializeScalar in constant time
can leak information about the underlying corresponding Scalar.¶
As an optimization, if the group order is very close to a power of
2, it is acceptable to omit the rejection test completely. In
particular, if the group order is p, and there is an integer b
such that p - 2<sup>b</sup>| < 2<sup>(b/2)</sup>, then
RandomScalar can simply return a uniformly random integer of at
most b bits.¶
Generate a random byte array with L = ceil(((3 * ceil(log2(G.Order()))) / 2) / 8)
bytes, and interpret it as an integer; reduce the integer modulo G.Order() and return the
result. See [I-D.irtf-cfrg-hash-to-curve], Section 5 for the underlying derivation of L.¶
This section describes considerations for applications, including external interface recommendations, explicit error treatment, and public input representation for the POPRF protocol variant.¶
Application inputs, expressed as PrivateInput or PublicInput values, MUST be smaller than 2^13 bytes in length. Applications that require longer inputs can use a cryptographic hash function to map these longer inputs to a fixed-length input that fits within the PublicInput or PrivateInput length bounds. Note that some cryptographic hash functions have input length restrictions themselves, but these limits are often large enough to not be a concern in practice. For example, SHA-256 has an input limit of 2^61 bytes.¶
In Section 3.3, the interface of the protocol functions allows that some inputs (and outputs) to be group elements and scalars. However, implementations can instead operate over group elements and scalars internally, and only expose interfaces that operate with an application-specific format of messages.¶
Some OPRF variants specified in this document have fallible operations. For example, Finalize
and BlindEvaluate can fail if any element received from the peer fails input validation.
The explicit errors generated throughout this specification, along with the
conditions that lead to each error, are as follows:¶
VerifyError: Verifiable OPRF proof verification failed; Section 3.3.2 and Section 3.3.3.¶
DeserializeError: Group Element or Scalar deserialization failure; Section 2.1 and Section 3.3.¶
InputValidationError: Validation of byte array inputs failed; Section 4.¶
There are other explicit errors generated in this specification; however, they occur with negligible probability in practice. We note them here for completeness.¶
InvalidInputError: OPRF Blind input produces an invalid output element; Section 3.3.1 and Section 3.3.3.¶
InverseError: A tweaked private key is invalid (has no multiplicative inverse); Section 2.1 and Section 3.3.¶
In general, the errors in this document are meant as a guide to implementors. They are not an exhaustive list of all the errors an implementation might emit. For example, implementations might run out of memory and return a corresponding error.¶
Functionally, the VOPRF and POPRF variants differ in that the POPRF variant admits public input, whereas the VOPRF variant does not. Public input allows clients and servers to cryptographically bind additional data to the POPRF output. A POPRF with fixed public input is functionally equivalent to a VOPRF. However, there are differences in the underlying security assumptions made about each variant; see Section 7.2 for more details.¶
This public input is known to both parties at the start of the protocol. It is RECOMMENDED that this public input be constructed with some type of higher-level domain separation to avoid cross protocol attacks or related issues. For example, protocols using this construction might ensure that the public input uses a unique, prefix-free encoding. See [I-D.irtf-cfrg-hash-to-curve], Section 10.4 for further discussion on constructing domain separation values.¶
Implementations of the POPRF may choose to not let applications control info in
cases where this value is fixed or otherwise not useful to the application. In this
case, the resulting protocol is functionally equivalent to the VOPRF, which does not
admit public input.¶
This document has no IANA actions.¶
This section discusses the security of the protocols defined in this specification, along with some suggestions and trade-offs that arise from the implementation of the protocol variants in this document. Note that the syntax of the POPRF variant is different from that of the OPRF and VOPRF variants since it admits an additional public input, but the same security considerations apply.¶
The security properties of an OPRF protocol with functionality y = F(k, x) include those of a standard PRF. Specifically:¶
In other words, consider an adversary that picks inputs x from the domain of F and evaluates F on (k, x) (without knowledge of randomly sampled k). Then the output distribution F(k, x) is indistinguishable from the output distribution of a randomly chosen function with the same domain and range.¶
A consequence of showing that a function is pseudorandom is that it is necessarily non-malleable (i.e. we cannot compute a new evaluation of F from an existing evaluation). A genuinely random function will be non-malleable with high probability, and so a pseudorandom function must be non-malleable to maintain indistinguishability.¶
In other words, an attacker with infinite computing power cannot recover any information about the client's private input x from an invocation of the protocol.¶
Essentially, input secrecy is the property that, even if the server learns the client's private input x at some point in the future, the server cannot link any particular PRF evaluation to x. This property is also known as unlinkability [DGSTV18].¶
For the VOPRF and POPRF protocol variants, there is an additional security property:¶
Any VOPRF or POPRF that satisfies the 'verifiable' security property is known as 'verifiable'. In practice, the notion of verifiability requires that the server commits to the key before the actual protocol execution takes place. Then the client verifies that the server has used the key in the protocol using this commitment. In the following, we may also refer to this commitment as a public key.¶
Finally, the POPRF variant also has the following security property:¶
This property becomes useful when dealing with key management operations such as the rotation of server's keys. Note that partial obliviousness only applies to the POPRF variant because neither the OPRF nor VOPRF variants accept public input to the protocol.¶
Below, we discuss the cryptographic security of each protocol variant from Section 3, relative to the necessary cryptographic assumptions that need to be made.¶
The OPRF and VOPRF protocol variants in this document are based on [JKK14]. In particular, the VOPRF construction is similar to the [JKK14] construction with the following distinguishing properties:¶
The pseudorandomness and input secrecy (and verifiability) of the OPRF (and VOPRF) protocols in [JKK14] are based on the One-More Gap Computational Diffie Hellman assumption that is computationally difficult to solve in the corresponding prime-order group. In [JKK14], these properties are proven for one instance (i.e., one key) of the VOPRF protocol, and without batching. There is currently no security analysis available for the VOPRF protocol described in this document in a setting with multiple server keys or batching.¶
The POPRF construction in this document is based on the construction known as 3HashSDHI given by [TCRSTW21]. The construction is identical to 3HashSDHI, except that this design can optionally perform multiple POPRF evaluations in one batch, whilst only constructing one DLEQ proof object. This is enabled using an established batching technique [DGSTV18].¶
Pseudorandomness, input secrecy, verifiability, and partial obliviousness of the POPRF variant is
based on the assumption that the One-More Gap Strong Diffie-Hellman Inversion (SDHI)
assumption from [TCRSTW21] is computationally difficult to solve in the corresponding
prime-order group. Tyagi et al. [TCRSTW21] show that both the One-More Gap Computational Diffie Hellman assumption
and the One-More Gap SDHI assumption reduce to the q-DL (Discrete Log) assumption
in the algebraic group model, for some q number of BlindEvaluate queries.
(The One-More Gap Computational Diffie Hellman assumption was the hardness assumption used to
evaluate the OPRF and VOPRF designs based on [JKK14], which is a predecessor
to the POPRF variant in Section 3.3.3.)¶
A side-effect of the OPRF protocol variants in this document is that they allow
instantiation of an oracle for constructing static DH samples; see [BG04] and [Cheon06].
These attacks are meant to recover (bits of) the server private key.
Best-known attacks reduce the security of the prime-order group instantiation by log_2(Q)/2
bits, where Q is the number of BlindEvaluate calls made by the attacker.¶
As a result of this class of attacks, choosing prime-order groups with a 128-bit security
level instantiates an OPRF with a reduced security level of 128-(log_2(Q)/2) bits of security.
Moreover, such attacks are only possible for those certain applications where the
adversary can query the OPRF directly. Applications can mitigate against this problem
in a variety of ways, e.g., by rate-limiting client queries to BlindEvaluate or by
rotating private keys. In applications where such an oracle is not made available
this security loss does not apply.¶
In most cases, it would require an informed and persistent attacker to launch a highly expensive attack to reduce security to anything much below 100 bits of security. Applications that admit the aforementioned oracle functionality, and that cannot tolerate discrete logarithm security of lower than 128 bits, are RECOMMENDED to choose groups that target a higher security level, such as decaf448 (used by ciphersuite 0x0002), P-384 (used by 0x0004), or P-521 (used by 0x0005).¶
Applications SHOULD construct input to the protocol to provide domain separation. Any system which has multiple OPRF applications should distinguish client inputs to ensure the OPRF results are separate. Guidance for constructing info can be found in [I-D.irtf-cfrg-hash-to-curve], Section 3.1.¶
To ensure no information is leaked during protocol execution, all
operations that use secret data MUST run in constant time. This includes
all prime-order group operations and proof-specific operations that
operate on secret data, including GenerateProof and BlindEvaluate.¶

This section includes test vectors for the protocol variants specified in this document. For each ciphersuite specified in Section 4, there is a set of test vectors for the protocol when run the OPRF, VOPRF, and POPRF modes. Each test vector lists the batch size for the evaluation. Each test vector value is encoded as a hexadecimal byte string. The fields of each test vector are described below.¶
Blind(), a serialized Scalar
of Ns bytes long.¶
Blind(), a serialized
Element of Ne bytes long.¶
BlindEvaluate(),
a serialized Element of Ne bytes long.¶
Proof output from GenerateProof() composed of
two serialized Scalar values each of Ns bytes long. Only present for
VOPRF and POPRF test vectors.¶
r computed in GenerateProof(), a
serialized Scalar of Ns bytes long. Only present for VOPRF and POPRF
test vectors.¶
Nh bytes.¶
Test vectors with batch size B > 1 have inputs separated by a comma ",". Applicable test vectors will have B different values for the "Input", "Blind", "BlindedElement", "EvaluationElement", and "Output" fields.¶
The server key material, pkSm and skSm, are listed under the mode for
each ciphersuite. Both pkSm and skSm are the serialized values of
pkS and skS, respectively, as used in the protocol. Each key pair
is derived from a seed Seed and info string KeyInfo, which are
listed as well, using the DeriveKeyPair function from Section 3.2.¶
