Abstract :This article presents an algorithm for the generation of S-boxes with the maximum algebraic immunity and high nonlinearity. The algorithm is founded method of the permutation of output element of S-box. On basis of the proposed method, $Sinsert ignore into journalissuearticles values(8\times 8);$-box created, with the algebraic immunity 3 insert ignore into journalissuearticles values(441); and nonlinearity 104. The algorithm given in this article can be used for oscillation of $Sinsert ignore into journalissuearticles values(8\times 8);$);-boxes with the increased resistance to algebraic, linear, differential and linear and differential methods of a cryptanalysis, for block symmetric algorithms of encryption.
Keywords : S box, algebraic cryptanalysis, algebraic immunity, nonlinearity
