Abstract 

This research work proposes peculiarities of construction of modified block ciphers on the basis of inclusion of masking symbols. The analysis of effectiveness of the proposed block ciphers using the National Institute of Standards and Technology (NIST USA) statistical tests is done. Increasing of block ciphers’ effectiveness is described
