Crypto-Forum RG Report CFRG serves as a bridge between theory and practice, bringing new cryptographic techniques to the Internet community and promoting an understanding of their use and applicability. It is a forum for discussing and analyzing general cryptographic aspects of security protocols. IETF working groups developing protocols that include cryptographic elements often find it useful to bring questions to CFRG. Current Work We discussed Message Authentication Code (MAC) requirements, both in the context of draft-irtf-cfrg-fast-mac-requirements and the TCP-AO that is currently under design in the TCPM WG. New work that makes digital signatures less vulnerable to attacks against hash functions (such as SHA-1 and MD5) was presented in draft-irtf-cfrg-rhash-01.txt. Some new work, draft-dharkins-siv-aes-01, was reviewed, discussed, and revised. This work presents a new method for authenticated encryption that is more robust against misuse than most other modes. It is under consideration in TLS WG and other areas. The draft "An Interface and Algorithms for Authenticated Encryption" was approved for RFC. This work has been adopted by the TLS WG as the basis for its use of AES GCM, and it being adopted for other IETF uses as well. Future Work We expect that a discussion of MAC candidates will follow the discussion of MAC requirements. References to some candidates have already been provided. http://www.irtf.org/cfrg http://www.irtf.org/rg/cfrg/ _______________________________________________ IRTF-Announce mailing list IRTF-Announce@ietf.org http://www.ietf.org/mailman/listinfo/irtf-announce
