A draft version of the SAML 2.0 Information Card Token Profile has been submitted to the OASIS Security Services (SAML) TC. "Microsoft has defined a set of profiles for acquring and delivering security tokens, collectively referred to as 'Information Card' technology. These profiles are agnostic with respect to the format and semantics of a security token, but interoperability between issuing and relying parties cannot be achieved without additional rules governing the creation and use of the tokens exchanged. This profile describes a set of rules for identity providers and relying parties to follow when using SAML 2.0 assertions as managed information card security tokens, so that interoperability and security is achieved commensurate with other SAML authentication profiles...
Identity providers and relying parties employing the Identity Selector Interoperability Profile V1.0 (ISIP -Microsoft) to request and exchange security tokens are able to use arbitrary token formats, provided there is agreement on the token's syntax and semantics, and a way to connect the token's content to the supported protocol features. This profile provides a set of requirements and guidelines for the use of SAML 2.0 assertions as security tokens that, where possible, emulates existing SAML 2.0 authentication profiles so as to limit the amount of new work that must be done by existing software to support the use of Information Cards. It also provides for the use of SAML assertions in this new context that is safe, and consistent with best practices in similar contexts.
