NIST SP 800-22: Download Documentation and Software

• April 27, 2010: NIST SP 800-22rev1a (dated April 2010), A Statistical Test Suite for the Validation of Random Number Generators and Pseudo Random Number Generators for Cryptographic Applications, that describes the test suite.

  July 9, 2014: This update has a few minor corrections to the source code. The first change corrects the non-overlapping template test to make it correctly skip bits when a sequence matches.  The second change is to correct the π values in the overlapping template test.

• Software Revision History
  • August 11, 2010: NIST has released a minor update to the tool. The update is called sts-2.1.1. This update makes a minor change in the proportions value in the finalAnalysisReport.txt file. This value is now printed as a fraction of sequences passing the tests.
  • April 27, 2010: NIST has released a minor update to the tool. The update is called sts-2.1. The update fixes a problem with the Spectral Test. Additionally, it is recommended that the Spectral Test only be used for sequence lengths of 1,000,000 bits.

Note: When using the samples from the data/ directory to derive the values from Appendix B the suite should be invoked with a stream length of 1,000,000 bits and there is one stream per file. For the tests that have parameters the default values should be used. Additionally, the results from the tables in Appendix B are not found in the finalAnalysisReport.txt file. They are in the results.txt files in the individual test directories (when running the sample data files these test directories are in the directory experiments/AlgorithmTesting/
