(k) Attribute Predicate Profile (added to agenda)

Franz-Stefan Preiss introduced Attribute Predicate Profile.

IBM working in privacy, wish to have support for predicate over attributes as opposed to simply concrete values. Draft profile produced for SAML assertions, also query format.
Canonical example of restricting age for access to chat room. This enables new privacy-protecting functionality.

see http://www.oasis-open.org/apps/org/workgroup/security/email/archives/201103/msg00022.html

Profile builds on XACML to express predicates, the XACML apply element to apply function to arguments. This enables arbitrary complex predicates over any number of arguments.

Added new statement type, AttributePredicateStatementType.

No changes to SAML standards, normal extension points used, hence a profile. Question as to whether this should be standardized in SSTC - TC members note that a profile like this can be standardized in SSTC. It might make sense to split SSTC and XACML portions for separate approval in the respective TCs - whether this should be done needs review.  The TC discussed whether or not to reduce the number of predicates allowed.

This submission should be uploaded into the SSTC document archive. 

Request for review and discussion on next call.  

5. Assorted mail items:

reminders, NIST IDtrust 2011,  IETF next week.

6. Other items:


7. Next SSTC Call: 
  - Tue 5 April 2011.
