Abstract
A finite field parallel multiplier in GF(q.sup.m) including a router for directing 2m-1 components in m groups of m single-component signal lines towards m computing circuits for performing multiply and add modulo-q. The router guides m components from a first finite field element along with an additional m-1 components generated from linear combinations of the m components of the first finite field element. Each of the computing circuits receives all of the components from the second finite field element and m components provided by one set of signal lines through the router. Each computing circuit generates a single component for the resultant finite field element. These resulting components may be input through a basis change circuit to obtain a result in the desired basis.
