Novel Approach Design of Elliptic curve Cryptography Implementation in VLSI

This paper presents an area efficient FPGA implementation approach of the elliptic curve cryptography. There are many retreats in current encryption algorithms (RSA; AES) in respect of security, power & resources at real-time performance [6]. The Elliptic Curve cryptography (ECC) is developing as an important cryptography, and shows a promise to be an alternative of RSA. Small size, high security and other features characterize ECC. Based on the theory of ECC, this paper analyzes its advantages over other cryptographies and focuses on its principle.
