The paper is devoted to a research of modern block cryptoalgorithms statistical secure. The influence of each nonlinear round function step on transformed sequence statistical properties is analyzed. Theoretical calculations of the minimum rounds quantity necessary for full information dispersion and hashing are performed. The experimental results of modern stochastic algorithms nonlinear function mixing properties including with use of NIST and graphic tests are given. The improvement options of round function diffusive properties are also offered.
