Models and calculable methods of forming of nonlinear knots of replacements are explored for symmetric cryptographic facilities of defence of information. The probabilistic model of forming of nonlinear knots of replacements is developed, in basis of which the probabilistic selection of cryptographic functions lies with the required indexes of firmness. Efficiency of the offered method is explored, it is shown that his use allows to build functions with the best cryptographic types known for today.
