Abstract(in English) | In this paper, an algorithm using look-up table based on extended Euclid's algorithm for computing inversion in GF(2^m) is proposed. In this algorithm, operations corresponding to several contiguous iterations of the conventional algorithm are represented in an array. To speed up the computation, this array is precomputed and stored in a look-up table. An inverter in GF(2^m) based in this algorithm has a the number of XOR stages reduced. Moreover, the processing time of a multiple-precision inversion over GF(2^m) in software implementation can be reduced using a w × (w + l)-bit multiplier over GF(2^m). |
