The development of information technologies and the need to protect information indicate the relevance of developing new cryptographic algorithms, such as block ciphers with different block sizes that correspond to modern requirements for cryptographic stability and performance. This paper presents the results of experimental studies of algorithm 256-3 performance (block size is 256 bits), proposed by Russian researchers in 2018. This paper provides a performance comparison between 256-3 and well-known block ciphers. The comparison has been conducted by running implementations of algorithms in C++ programming language using Crypto++ library. The results showed that the 256-3 algorithm runs around 24.57 cycles per byte and performance of 256-3 from 1.2 to 2.6 times higher than the performance of the algorithms Magma (GOST 28147-89), Kuznyechik (GOST 34.12-2018), SEED, HIGHT, Camellia-256, Kalyna-256/256, MARS-256, CAST-256, which indicates that 256-3 is a positive (from the synthesis position).
Keywords: block cipher performance, block ciphers benchmarks, GOST, Kuznyechik, AES, Rijndael, SEED, SM4, HIGHT, Camellia, Kalyna, CAST, Crypto++.
