Construction of Multidimensional Stochastic Transformation Blocks

Abstract

The article is devoted to the improvement of stochastic transformation blocks (R-blocks). The principles of R- blocks construction are considered. We review the examples of R- blocks using in the cryptographic algorithms. The structure of two-dimensional stochastic transformation block is proposed, as well as the method for construction of multidimensional R- blocks. The using of improved R-blocks for construction of multidimensional algorithms is proposed. The results of evaluation of statistical properties of the multidimensional stochastic transformation blocks are given.
