Abstract(in English) As effective arithmetic methods in the finite field GF(2^m), M.A. Hasan has presented a look-up table-based algorithm for GF(2^m) multiplication. In Hasan's method, the number of memory access and the table size are depend on the form of the irreducible polynomial which is used in the GF(2^m) multiplication. In this paper, we propose a lookup-up table-based algorithm which can be performed as an efficient GF(2^m) multiplication using the irreducible polynomial which has m degree and m terms. In this method, the algorithm is performed as the multiplication modulo quadnomial which is obtained by the irreducible polynomial which has m degree and m terms. Using this method, the number of memory access and the table size in the algorithm is smaller than that in Hasan's method, and GF(2^m) multiplication is faster than Hasan's method.
