It has been patented throughout the world." Okay, this is the second time I've heard this, and it doesn't make sense to me. I thought Diffie and Hellman invented (and published) public-key cryptography before RSA was invented? Do I have a misunderstanding (feel free to correct me), or is it just PKC that is based on the difficulty of factoring that is covered by the PKP patent? (Or did I misidentify the patent number above?) --Ken Pizzini
