Computational aspects of the expected differential probability of 4-round AES and AES-like ciphers (Q2390943)

The authors study the security of the AES and AES-like block cipher against differential cryptanalysis. They start with a general presentation of basic terms and mathematical background of the AES encryption model and continuing by studying particular characteristic of the cipher system show the security of \(S\)-boxes against differential attack. The entire work represents a good exposure of the AES model study and can be a part of cryptographically analysis in order to improve the security of the model in certain cases.
