Hi everyone, I'm trying to implement security in an agent based auction system (MAGNET), in which a submitter sends a bid encrypted with a session key, which in turn is encrypted using time-lock crypto. The session key is sent after the auction is complete. My problem is generating an individual symmetric key which can be used as a session key. I looked at all symmetric crypto functions, but didn't seem to find one that could generate a key on its own. Maybe I overlooked something. Anyone have any suggestions? thanks, Ashu -- http://www.jaiashu.com/ ------------------------------------- "I would like to change the world, but they wont tell me the source code" |
