Materials submitted for additional substantiation of the validity of the hypothesis that large codes are asymptotically random permutations. Now compare the statistical properties of each series of advanced ciphers and reduced models with Test NIST STS. Among them are considered ciphers submitted to the Ukrainian competition, and finalist of AES cipher Rijndael. It is established that the examined parameters Ukrainian ciphers Kalina, Amanita, and Maze exceed the recognized world leader block symmetric encryption cipher AES.
provable resistance, tests NIST STS, accident rates, and a prototype model, the random substitution cipher model is reduced
