Panchami V, Varghese Paul, Amitabh Wahi

International Journal of Communication Systems > 30 > 16 > n/a - n/a

In cryptography, S‐boxes play an important role in symmetric ciphers. S‐boxes are used for substitution process to enable diffusion in encryption and decryption of the messages. In most of the conventional and modern symmetric ciphers, the S‐boxes are of static in nature. It will never depend or vary with respect to the message or the key, but dynamic S‐boxes are more resistant to linear and differential...
