Abstract

We propose a new linear multiplier which is comparable to linear polynomial basis multipliers in terms of the area and time complexity. Also we give a very detailed comparison of our multiplier with the normal and polynomial basis multipliers for the five binary fields GF(2m), m=163,233,283,409,571, recommended by NIST for elliptic curve digital signature algorithm.
