Abstract
A composite finite field multiplier is disclosed. The multiplier includes a controller, an input port, an output port, a GF((2)) multiplier, a GF(2) standard basis multiplier, and a GF(2) look-up table multiplier; the controller is connected respectively to the input port, the output port, the GF((2)) multiplier, the GF(2) standard basis multiplier and the GF(2) look-up table multiplier; the GF((2)) multiplier is connected respectively to the GF(2) standard basis multiplier and the GF(2) look-up table multiplier. By using the GF((2)) multiplier, the GF(2) standard basis multiplier and the GF(2) look-up table multiplier, the multiplication of three operands is realized. Compared with the existing multiplier, the multiplier of the present invention has significant advantages in the speed of multiplying three operands over GF((2)).
