Hi Kenny:

I had some trouble finding recent discussions on this document. The 
document seems to have dependencies on other drafts (e.g., Ristretto) 
for which it is very hard to find any discussion either (and are not 
that easy to read ). If you could point to this, that would be great.

Could you explain how this fits within CFRG's charter? What is the 
general philosophy nowadays ("more is better" vs. "less is more", 
protocols with wide applicability vs. specialized, etc, etc.)?

Best regards, Rene

[excerpted from]

The Crypto Forum Research Group (CFRG) is a general forum for discussing 
and reviewing uses of cryptographic mechanisms, both for network 
security in general and for the IETF in particular.

The CFRG serves as a bridge between theory and practice, bringing new 
cryptographic techniques to the Internet community and promoting an 
understanding of the use and applicability of these mechanisms via 
Informational RFCs (in the tradition of, e.g., RFC 1321 (MD5) and RFC 
2104 (HMAC). Our goal is to provide a forum for discussing and analyzing 
general cryptographic aspects of security protocols, and to offer 
guidance on the use of emerging mechanisms and new uses of existing 
mechanisms. IETF working groups developing protocols that include 
cryptographic elements are welcome to bring questions concerning the 
protocols to the CFRG for advice.

Meetings and Membership

The CFRG meetings, membership, and mailing list are open to all who wish 
to participate.
