I disagree. I was referring to the *standard* case (no point compression, no special performance tweaks). If you're building something high performance, choosing special curves, etc., you're in a different playing field. Whether it's possible to do an efficient implementation in hw without resorting to those techniques is a very specific question that I won't answer here. I won't go into any more detail since it's not a good policy to publicly discuss patents. I just wanted to respond to the FUD that the original poster was spreading re: EC being covered by patents that had expired. -- Nate --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
