Properties of the Controlled Substitution-Permutation Network for Block Encryption Algorithm Based on One Class of Permutations

Article is devoted to investigation of the controlled substitution-permutation network based on managed elements F_4/2 as a primitive block encryption algorithms. Relevance of research is related to their focus on the design of high-speed hardware ciphers. The scientific and practical significance of the results is to improve the efficiency of high-speed hardware implementation of encryption algorithms, designed to protect information in information and telecommunication systems and networks.
