* in broad terms, what would I have to do to develop an algorithm that works from a user's perspective like p.k.c. (ie public/private keys, the central functional point of all the wonderful schemes based on pkc) but doesn't violate patents? L.

derek@cs.wisc.edu (Derek Zahn) this appears to be a simple technical question on one level. What does it take to come up with a good public key system?

How about a poor public key system? What is the simplest public key system you can invent, if you didn't care that it is trivial to break? If the NSA can crack RSA, does that change the fact that it is a pkc? message=99 public_key= 1/3 private_key= 3 encrypted_message= message * public_key message= encrypted_message * private_key Would PKP reading of their patent claims cover this pkc? Seems overbroad! Peter Baumbach baumbach@atmel.com
