General results

The Diehard test is a set of statistical tests used to evaluate the quality of a random number generator. The results show that all the tests were “PASSED”, meaning that they passed and revealed no significant problems in the random number generation.

Key points to consider

  • All tests obtained p-values greater than 0.05, indicating that no test detected a statistically significant difference from a uniform distribution.

  • Most tests have p-values close to 0.5, which is expected for a uniform distribution.

  • Some tests like rgb_bitdist (p-value = 0.99998118) and dab_bytedistrib (p-value = 0.23859982) have slightly higher p-values, but still above 0.05.

Analysis of specific tests

  • Basic tests such as diehard_birthdays, diehard_operm5, diehard_rank_32x32, etc. all passed, which is encouraging for the overall quality of the generator.

  • The rgb_bitdist test for entropy 4, where the p-value is 0.00001882, which is extremely low. This means that the test has failed and is "WEAK". This test measures the distribution of bits in groups of bits over several positions and indicates an irregularity or systematic trend in the distribution of bits for that specific entropy.

  • The dab_bytedistrib test has a p-value of 0.23859982, which is slightly higher but still within the acceptance range.

  • On the whole, however, TRNG seems to be performing well.

Conclusion

In summary, these results indicate that the random number generator under test appears to function correctly according to the Diehard tests. All tests were passed, with p-values consistent with a uniform distribution. CAUTION: For critical applications requiring a high level of security, further tests could be considered.
