Abstract

Conventional Elliptic Curve (EC) cryptosystems are subjected to side channel attacks because of their lack of unifiedness. On the other hand, unified cryptosystems based on Edwards curves have been found to be slow. The present paper proposes the first VLSI design of binary Huff curves, which also lead to unified scalar multiplication. Several optimized architectural features have been developed to utilize the FPGA resources better, and yet lead to a faster circuit. Experimental results have been presented on the standard NIST curves, and on state-of-the-art GF(2233) to show that the design is significantly faster than other unified EC cryptosystems.
