The article contains a computationally effective method for determining averaged distribution of differentials for pseudo-dynamic substitutions PD-Sbox. That opens the possibility of an effective search and synthesis of pseudo-dynamic substitutions PD-sbox with optimal characteristics. Search and further study of cryptographic properties of such substitutions will significantly improve the effectiveness of the pseudo-dynamic substitutions PD-sbox in symmetric cryptoalgorithms.
