It is advertised as a work in progress, so I'm sure future efforts will include a bit more about prior technical work. Authenticating email senders is a very good idea -- and it was a very good idea when described by Roger Needham (recently deceased) and Mike Schroeder 25 years ago. If people are interested in early work on this topic, they might enjoy the original paper, "Using encryption for authentication in large networks of computers," published in the CACM in Dec. 1978. I'm sure it is available in other places, but I found an on-line version at: http://lambda.cs.yale.edu/cs422/doc/needham.pdf. One of the functions they describe is, "Authenticated one-way communication, such as is found in mail systems...." Furthermore, these early ideas were actually implemented in the Xerox/XNS internet protocols and mail system. You might receive an email from "Farber@xxx (unauthenticated)" or from "Farber@xxx (authenticated by abc)" -- and you could react accordingly. There has been a lot more work following the Needham & Schroeder paper, and of course the environment has gotten a LOT more complex (I won't even touch the political and business problems). But I hope we don't completely lose track of where we came from. (Remember, there were other internetworks besides "the Internet" and there were other mail architectures besides SMTP.....)
