Özet:

Randomness is one of the most important parts of the cryptography because key generation and key itself depend on random values. In literature, there exist statistical randomness tests and test suites to evaluate randomness of the cryptographic algorithm. Although there exist randomness tests, there is no mathematical evidence to prove that a sequence or a number is random. Therefore, it is vital to choose tests in the test suites due to independency and coverage of the tests used in the suites. Sensitivity of these tests to non-random data is also important. The tests should be classified to determine that tests are independent and wide. In order to classify, sensitivity of tests to transformations and to nonrandom data should be determined. Therefore, mutual correlations of tests are analyzed.
