The article presents the EPES8–2 network with two round functions using the same algorithm for encryption and decryption.

Currently, block encryption algorithms based on the Feystel network are widely used. Block encryption algorithms based on the Feystel network include encryption algorithms such as DES, GOST 28147-89, as well as block encryption algorithms such as CAST 256, DFC, E2, LOKI97, which participated in the competition announced by NIST. The advantage of this network is that a single algorithm is used for encryption and decryption, only the encryption round keys are used in reverse order for decryption.
