Abstract

This paper presents a new parallel multiplier for the Galois field $GF(2^m)$ whose elements are represented using the optimal normal basis of type II. The proposed multiplier requires $1.5(m^2-m)$ XOR gates, as compared to $2(m^2-m)$ XOR gates required by the Massey-Omura multiplier. The time complexities of the proposed and the Massey-Omura multipliers are similar.
