A Systematic Approach of NIST Statistical Tests Dependencies



In order to evaluate binary strings generated by cryptographic applications, for randomness and unpredictability, an instrument may be the statistical tests. Because in terms of probability it cannot be assumed that these statistical tests are completely reliable/effective, they must be tested for uniformity, scalability, and consistency, searching for any kind of correlation that might affect their desired properties and their results. In this paper we proposed a systematic approach of testing and analyzing results concerning the NIST statistical test suite, determining dependencies between tests, and finding patterns for the evolution of these dependencies according to specific factors, such as binary string length.
