Date: Fri, 25 Jun 1999 01:12:44 +0100 From: Adam Back <aba@dcs.ex.ac.uk> To: cryptography@c2.net Cc: coderpunks@c2.net Are there any elliptic curve systems and parameter sets which it is possible to use on a world wide basis? IEEE P1363 curves and parameters? Are there libraries licensable worldwide which implement any of these? Are there freeware or other licensed libraries? I am aware of Wei Dei's crypto++ v3.1 which is tracking p1363 ( grumble: it's documentation is non-existant). ftp://www.replay.com/pub/replay/crypto/LIBS/crypto/ Also there is pegwit, and Mike Rosings elliptic packages which I haven't looked at yet. The basic question is really is there a simple way to: - obtain an EC library - which has no patent restrictions in US or anywhere else - or license a library (which has patent retrictions) and still be able to use it in US or anywhere else Do the certicom people have a library? Also NIST offers: June 1999 - Recommmended Elliptic Curves in ASCII http://csrc.nist.gov/encryption/CURVES.txt Are they suggesting that if/when they do a FIPS on EC, they will all and any of the listed curves and parameters? Are all of these parameters patent and copyright free? Adam
