In this paper, a cryptanalysis method that combines chosen-ciphertext attack with divide-and-conquer by traversing multiple nonzero component initial conditions (DCA-TMNCIC) is proposed. The used for security analysis of [Formula: see text]-D ([Formula: text]) self-synchronous chaotic stream ciphers employ product two variables and three SCSC-2 SCSC-3), taking 3-D as typical example cryptanalys...

Abstract The primary objective of this work is to develop an algorithm for detecting the secret round key used in encryption by analyzing a collection plaintexts and ciphertexts encrypted with three-round Kuznyechik algorithm. In addition, fundamentals using integral cryptanalysis method Substitution-permutation (SP) network-based have been investigated. It has found that useful creating balanc...
