There are several combinations of key exchange methods, it was pointed out that this is an example of the combinatorial cyphersuite problem we chose not to solve when the TLS draft was written. There are a total of 49 cipher suites. It was observed that the servers would have to have possibly multiple certificates depending on which curves are used. There are patents involved with this. Discussion went on as to whether this draft should go on the standards track or not.
Issues are connection closure and endpoint identification.
Attribute certificates to allow role-based access control and access control forwarding. This is discussed in the TLS context because you need an authenticated, secure infrastructure to support this. The content and usage of Attribute Certificates was discussed. There was discussion from the floor. There were questions regarding the set of requirements described in this draft.
