STUDY OF THE CRYPTO STRENGTH OF THE S-BOX USED IN THE AL03 ENCRYPTION ALGORITHM

The study of the cryptographic strength of S-boxes used in symmetric block cryptosystems is one of the most important tasks in the development and analysis of encryption algorithms. In this article, a study was carried out on the nonlinearity and strict avalanche criterion (SAC) of the S-box used in the AL03 encryption algorithm. The results of the study were compared with the S-boxes of modern cryptographic algorithms and showed good results.
