I believe Koblitz curves are dense with 1's, unlike NIST which are sparse or have few 1's (low hamming weight). Koblitz curves are useful depending on your optimization tricks as I understand it. You will need to check though, if it really matters. Jeff -- You received this message because you are subscribed to the "Crypto++ Users" Google Group.
