I have been told that there is a new improved version of DH key exchange, which is authenticated. Could someone give me the reference, and/or tell me what it is all about?........ Diffie?? I was not clear on what it is that I am working on. We are trying to build a cheep secure phone for the masses (read brainless). We are looking for black box brainless operation. I will provide more info about the project on request. ---------------------------------------------------------- Lance Cottrell who does not speak for CASS/UCSD loki@nately.ucsd.edu PGP 2.3 key available by finger or server.
