Implementation of elliptic curve digital signature algorithm (ECDSA)

The elliptic curve cryptosystems are paid more and more attention because its key string is shorter and its security is better than other public cryptosystems. The digital signature system based on elliptic curve (ECDSA) is one of the main stream digital signature systems. In this paper, we describe our proposed architecture to implement the ECDSA in FPGAs circuit. This architecture is planned to reach high performance running in FPGAs circuit. Synthesis results and relevant performance comparisons with related works are presented.
