Statistical analysis on enhanced 3D-AES block cipher cryptographic algorithm / Nor Azeala Mohd Yusof

Randomness test is one of the measurement techniques which have been taken into consideration in the evaluation of the minimum security requirement of the block cipher algorithm. A non-random block cipher seems to be vulnerable to any type of attack. Many algorithms such as AES, LED, KTANTAN, KATAN,...
