Abstract

An analysis of en/decryption GOST 28147-89 algorithm implementation variants' is carried out in order to determine the best variant at the early design stages. The algorithm field programmable array implementation 's(FPGA) output parameters evaluation is mainly considered. In order to evaluate the output parameters the two-level macromodeling method is used. It's usage enabled the substantial computational complexity reduction in comparison with known methods. It's shown that the results obtained using the two-level macromodeling method are adequate and precise enough. As a result of the carried out analysis the decision was taken to implement the algorithm using FPGA and the best, in the selected matter, device structure was determined.
