Байт-ориентированный алгоритм поточного шифрования на основе совокупности равномерно плотных блоков нелинейной подстановки

Abstract

Questions of construction of the new byte-oriented stream encryption algorithm, which encrypts the gamma-stochastic sequence of bits formed by a set of primitives uniformly dense nonlinear substitution. Evenly dense are called primitives, responses which are evenly distributed on the scatterplot. A comparative analysis of the efficiency of the developed and cryptographic transformation algorithm Rijndael-stream encryption mode. The directions of application of the proposed codes in various applications.
