Statistical test of cryptographic algorithms based on ANOVA

Abstract： In the field of cryptography, a random sequence is often used as a key, an initial vector or a time-varying parameter in cryptographic protocol. Actually, the randomness of a random sequence plays a very important role in the cryptography, since it determines the security of the whole system. The ciphertext sequence generated by a good cryptographic algorithm should not be distinguished by statistical methods. In this paper, we count the number of failures by using the national institute of standards and technology(NIST), which is executed on the ciphertext sequences generated by seven classic cryptographic algorithms. The analysis shows that the results are not statistically significant. Thus, the statistical test used in the paper can be used as one of the indicators to evaluate the quality of cryptographic algorithms.
