In any case, you can probably get all the information you are looking for in this manuscript: http://crypto.cs.mcgill.ca/~stiglic/Papers/dhfull.pdf Cheers! --Anton --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
