Abstract
A multiplier for obtaining the product of elements in a Galois Field. The multiplier performs the multiplication of two n-bit elements, A(a , a , . . . , a , a , a , a ) and B(b , b , . . . , b , b , b , b ) in the Galois Field to yield the product C(c , c , . . . , c , c , c , c ), wherein n≧1 a (i=0˜n-1), b (j=0˜n-1), and c (k=O˜n-1) are all binary bits. The multiplier includes: an AND planer, for performing an AND logic operation of every bit a in A(a , a , . . . , a , a , a , a ) and every bit b in B(b , b , . . . , b , b , b , b ) to obtain (a b , a b , . . . , a b , a b , a b , . . . , a b , a b , a b , . . . , a b ); and an XOR planer, for performing an XOR logic operation of the output from the AND planer to obtain C(c , c , . . . , c , c , c , c ).
