Analysis of the reasons of crisis of error-correcting coding. Grounded prospects for application of pseudorandom codes and developed their mathematical model. Considered comparative probabilistic characteristics of equal-length and normal casual codes. The evaluation of the properties of the simplest equal-length pseudo-random codes, which were received by method of the linear congruent generation. Proposed of recommendations on the choice of parameters of linear congruent generators code symbols.
