Sure. Because 1) it's a good algorithm for the job, 2) we've learned it, and have a PGP base behind our inertia, 3) The legalities of RSA are well-defined, 4) the Stanford patents mostly run out in 1997, unless Roger's suit succeeds first, 5) the price of RSA is fairly low, once free RSAREF came out 6) the price of licensing Cylink patents is high and/or unpredictable
I will add to Bill's list: 7) RSA is the best known and vetted of the Public Key algorithms. Some people say that the millennium comes on Jan 1, 2000. Others say it comes on January 1, 2001. I say it comes on September 20, 2000 when the RSA patent expires.

Nota at all, Mr. Frantz. There are no proofs of security associated with RSA. Rabin has excellent proofs that breaking a message is strictly equivalent to factoring. .pm

Isn't Rabin's algorithm patented, too? Perhaps the licensing terms are better. Does anyone know for sure? Thanks, David
What do you mean by "per se"? That it might be covered by the Stanford patents? (Those are the ones that allegedly cover all public-key, right?)

There is no patent on Rabin per se.

Rabin is covered by the patents on public key itself. It is the contention of RSA DSI that the patent on RSA claims all public key methods that use exponentiation. I do not believe this to be the case, but I am not the god of patents. There is no direct patent on Rabin, however. Perry
