Implementation Issues in Elliptic Curve based Cryptosystem

E.Karthikeyan, Dr. P. Balasubramaniam


Recently the study and implementation of Elliptic Curve Cryptosystems (ECC) have developed rapidly and its achievements have become center of attraction, because of the highest strength-per-key-bit of any known public key system. It is suitable for the constraint devices like mobile and handheld devices etc. The implementation of elliptic curve based cryptosystem is depends upon the selection of various parameters like field selection, field representation and elliptic curve arithmetic. In this paper we discuss the various implementation issues in detail.
