Interesting. At the NIST meeting, criteria #5 deals with decrypting a conversation with only the key from one end.

I thought that would be hard to implement. But during the discussion, they called on Miles Smid [sp?] who was obviously a NIST employee/consultant with real knowledge. He suggested that you could encrypt the session key with the public key of both parties, and send it along. This would allow single ended GAK.

Miles Smid is a NIST employee who is quite knowledgeable about crypto and Clipper.

This is not far from the idea that CME proposed that the NSA/FBI/CIA publish public keys, and we'll hack a voluntary version of PGP that encrypts the session key with the LEA public key -- instant voluntary Key Escrow.

I still think that's the only way the gov't will get GAK -- :) - Carl +--------------------------------------------------------------------------+ |Carl M.
