Abstract
A method and apparatus to square an element A when a defining polynomial of a finite field GF(2) is expressed as and the element A contained in the finite field is expressed as A=(a,a,a, . . . ,a)∈GF(2). The method determines coefficients m, I, V, V, and V such that the coefficient msatisfies a predetermined condition with respect to kwhen 1≦i≦t is a natural number, Idepends on n, k, and j when 2≦j≦m, Vand Vof n bits, respectively, depend on n, I, and k, and obtains the coefficient V with respect to maccording to the following formula determines a coefficient saccording to kand n and cyclically shifts the coefficient V by s; performing an XOR operation on the cyclically shifted coefficient V and the element A; and rewires a result of the XOR operation in a predetermined order and outputs results of the squaring.
