| Abstract | ||
| This paper provides analysis for different approaches used for security evaluation of some cipher systems. Many tests (computational complexity, statistical and Information theoretical ) are performed on the ciphered outputs of a number of classical cipher systems ranging from mono-alphabetic, to poly-alphabetic. The results were encouraging, and can be considered as an approach to enhance the security evaluation tasks (especially for the used skewness , kurtosis, unicity distance and the Key Entropy parameters), that is really considered as a hard problem facing the cryptosystem design. | ||
