A Modified Generation of S-Box for Advanced Encryption Standards

Data security is one of the pressing issues that needs to be addressed in this data-driven time. Enhancing techniques in data security can prevent attackers in launching attacks. AES is one of many cryptography tools that can be used in data security. S-box is one of the key parts and the only nonlinear part of AES. The paper enhanced S-box generation by combining its original S-box and an S-box generated by Logistic Map. Evaluation using avalanche effect shows that the results of encrypted texts using the modified S-box is 51% on average, better than 48% on average of the original.
