A Comparison on FPGA of Modular Multipliers Suitable for Elliptic Curve Cryptography over GF(p) for Specific p Values
Résumé
In this paper we provide a comparison of different modular multipliers suitable for use in an elliptic curve processor, when working with a Mersenne prime modulus. Mersenne primes allow for the use of fast modular reduction techniques. Several multipliers are presented that can be implemented solely in slice logic. A design that makes use of the DSP48E blocks on Virtex 5 FPGAs is also described. The different multipliers are compared for speed, area and power consumption when implemented on a Virtex 5 FPGA
