This operation is the finite field analogue of the Montgomery multiplication for modular multiplication of integers. We give the bit-level and word-level algorithms for computing the product, perform a thorough performance analysis, and compare the algorithm to the standard multiplication algorithm in GF(2^k). The Montgomery multiplication can be used to obtain fast software implementations of the discrete exponentiation operation, and is particularly suitable for cryptographic applications where k is large.}, url = {http://approjects.co.za/?big=en-us/research/publication/montgomery-multiplication-in-gf2k/}, pages = {57-69}, journal = {Designs, Codes and Cryptography}, volume = {14}, number = {1}, }
