AI 生成的摘要: The document reports the results of statistical randomness tests performed on a random number sequence generated by an embedded RNG in the RA4E2 device. Using the NIST SP 800-22 Revision 1a test suite and the sts-2.1.2 tool, the sequence passed all 15 statistical tests, including frequency, runs, and entropy tests, confirming its suitability for cryptographic applications. The test used a sequence length of 1,000,000 bits and a sample size of 1,000, with default significance levels. The report includes detailed pass proportions and P-values for each test, demonstrating compliance with NIST standards.
