Abstract
A method of obtaining C=(c, . . . , c) of a product of two elements A and B of a finite field GF(2). The method includes permuting the last d coefficients (a, . . . , a) of a multiplier A with predetermined variables (s, . . . , s); operating C:C=⊕(b●A) for (I+j)coefficient of a multiplicand B to update coefficients of C, where i and j are integers, and A:=(s)⊕(0,x●f, . . . ,s●f,0, . . . ,0) repeatedly for j=0 to (d−1) to update coefficients of A, where ⊕ represents an XOR operation and ● represents an AND operation; and repeatedly performing the permuting and operating by increasing i from 0 to (n−1) by d.
