Abstract

The Portable Symmetric Key Container (PSKC) contains a number of XML elements and XML attributes carrying keys and related information. Not all algorithms, however, are able to use all elements and for other algorithm certain information is mandatory. This lead to the introduction of PSKC algorithm profiles that provide further description about the mandatory and optional information elements and their semantic, including extensions that may be needed. The main PSKC specification defines two PSKC algorithm profiles, namely "HOTP" and "PIN". This document extends the initial set and specifies nine further algorithm profiles for PKSC.

[Editor's Note: The content of this document was created by moving a number of PSKC algorithm profiles from draft-ietf-keyprov-portable-symmetric-key-container-06.txt into this document. Since draft-ietf-keyprov-portable-symmetric-key-container-07.txt had experienced a number of changes the description and the examples in this document are likely to be out-of-sync. Re-alignment will be provided in a future version.]

2.  Terminology

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119] (, “Key words for use in RFCs to Indicate Requirement Levels,” March 1997.).

Profile of XML attributes and subelements of the <Key> entity:

For a <Key> of this algorithm, the <Usage> subelements MUST be present. The "CR" attribute of the <Usage> MUST be set "true" and it MUST be the only attribute set. The element <ChallengeFormat> and <ResponseFormat> of the <Usage> MUST be present.

- The <ResponseFormat> element MUST have the 'Format' attribute set to "DECIMAL", and the 'Length' attribute MUST be between 6 and 9.

- The <PINPolicy> element MAY be present but the <Format> child element of the <PINPolicy> element cannot be set to "Algorithmic".

Profile of XML attributes and subelements of the <Key> entity:

For a <Key> of this algorithm, the <Usage> subelements MUST be present. This algorithm can be used for otp, challenge response, parameter based MACing (integrity) and to generate a device unlock code (n case of devices where there is local PIN management and the devce has been locked after a specific amount of wrong PIN entry attempts). Hence the "OTP", "CR","Integrity" and "Unlock" attribute of the <Usage> can be set to "true", but at least one of the above MUST be set to true. The element <ResponseFormat> of the <Usage> MUST be used to indicate the OTP length, the value format and optionally if a check digit is being used. If the use is challenge-response then the <ChallengeFormat> of the <Usage> MUST be used to indicate the challenge minimum and maximum length, its format and optionally if a check digit is being used.

For the <Data> elements of a <Key> of this algorithm, the following subelements MUST be present in either the <Key> element itself or an commonly shared <KeyProperties> element.

The following additional constraints apply:

- The value of the <Secret> element MUST contain key material with a length of at least 16 octets (Double DES keys 128 bits including parity) if it is present.

- The <ResponseFormat> element MUST have the 'Format' attribute set to "DECIMAL" or "HEXADECIMAL", and the 'Length' attribute MUST be between 6 and 16.

- The <ChallengeFormat> element MUST have the 'Format' attribute set to "DECIMAL", and the 'Min' and 'Max' attributes be between 4 and 16 (The Min attribute MUST be equal or less than the Max).

- The <PINPolicy> element MAY be present but the <Format> child element of the <PINPolicy> element cannot be set to "Algorithmic".

Profile of XML attributes and subelements of the <Key> entity:

For a <Key> of this algorithm, the <Usage> subelements MUST be present. This algorithm can be used for otp, challenge response, parameter based MACing (integrity) and to generate a device unlock code (n case of devices where there is local PIN management and the devce has been locked after a specific amount of wrong PIN entry attempts). Hence the "OTP", "CR","Integrity" and "Unlock" attribute of the <Usage> can be set to "true", but at least one of the above MUST be set to true. The element <ResponseFormat> of the <Usage> MUST be used to indicate the OTP length, the value format and optionally if a check digit is being used. If the use is challenge-response then the <ChallengeFormat> of the <Usage> MUST be used to indicate the challenge minimum and maximum length, its format and optionally if a check digit is being used.

For the <Data> elements of a key of this algorithm, the following subelements MUST be present in either the <Key> element itself or an commonly shared <KeyProperties> element.

The following additional constraints apply:

- The value of the <Secret> element MUST contain key material with a length of at least 8 octets (56 bits + parity) if it is present.

- The <ResponseFormat> element MUST have the 'Format' attribute set to "DECIMAL" or "HEXADECIMAL", and the 'Length' attribute MUST be between 6 and 16.

- The <ChallengeFormat> element MUST have the 'Format' attribute set to "DECIMAL", and the 'Min' and 'Max' attributes be between 4 and 16 (The Min attribute MUST be equal or less than the Max).

- The <PINPolicy> element MAY be present but the <Format> child element of the <PINPolicy> element cannot be set to "Algorithmic".

An example of a <Key> of this algorithm is as follows.
