FPGA CORES FOR FAST MULTIPLICATIVE INVERSE CALCULATION IN GALOIS FIELDS

Abstract:

There are two common methods for division in a Galois Field GF(2^m): extended Euclidean algorithm for polynomial basis and exponentiation method for normal basis. The disadvantage of first is dependence of division time on the value of operands. So in the study some undependable on operand values methods based on fast multiplication are tested to select ones with the best hardware and time complexity for polynomial basis. All methods were implemented as FPGA cores, their work was verified by simulation.
