This page performs a chi-square test on Hytak TRNG to reduce test time. 100 runs correspond to 500,000 samples (100 runs × 5,000 samples), although NIST SP 800-90B officially requires 1,000,000 samples (1,000 restarts × 1,000 samples). This test is for quick verification only — not official NIST certification. Non-provisional patent filed by Faihoplo. ✅

NIST SP 800-90B Test Method

1
Hytak TRNG generates decimal digits (patent protected). Each sample = 4 digits = 13.2877 bits (log2(10) × 4)
2
Chi-square test on digits 0~9. Each should appear ~10%. χ² = Σ(observed-expected)²/expected
3
Pass criterion: χ² < 21.67 (critical value, df=9, α=0.01). P-value calculated for confidence level.
4
NIST SP 800-90B: Pass rate must exceed 95% over multiple runs. Our result: ~99% consistently.
