Аннотация:
A method of round key generation for iterated block ciphers based on a modified additive generator (MAG), and, in addition, on MAG and a linear congruent generator in a series circuit is proposed. The bijectivity of the generating transformation is demonstrated. Using the matrix-graph approach the number of iterations necessary for achieving enhanced cryptographic properties is experimentally evaluated. This number depends on the generator characteristics.
