Abstract
Two types of shared-field multipliers for performing multiplications on field elements of different sizes are presented. One type uses a “cyclic” Galois field GF(2 ), that is, a Galois field GF(2 ) generated by an irreducible polynomial x +x +x + . . . +x+1, and the other type uses a composite field structure. Each shared-field multiplier includes computation circuitry for receiving field elements as inputs, the computation circuitry being responsive to a control signal to perform computations based on the inputs having a first size to produce an output of the first size, or to perform computations based on the inputs having a second, different size to produce an output of the second size.
