Introduction
Analysis of the core content of the standard
| Detection method | Statistical principle | Key parameters | Application scenario |
|---|---|---|---|
| Single-bit frequency detection | Normal distribution test | Significance level α=0.01 | Basic balance verification |
| Matrix rank test | χ² distribution test | 32×32 matrix | Linear correlation analysis |
| Discrete Fourier test | Spectrum analysis | Threshold value√2.995732274n | Periodic feature detection |
Technology evolution analysis
This standard systematically integrates NIST SP800-22 and national secret algorithm requirements for the first time, and innovatively proposes approximate entropy detection and Maurer general statistical detection methods, and improves detection accuracy by introducing incomplete gamma function (igamc) and residual error function (erfc).
Implementation Suggestions
Judgment rules: The pass rate must be ＞98.1% (when α=0.01)
Typical configuration: Intra-block frequency detection recommends m=10000
Detection Principle Comparison
| Detection Type | Mathematical Tools | Sensitive Defects |
|---|---|---|
| Frequency Detection | Normal Distribution | 0/1 Ratio Imbalance |
| Structural Detection | χ² Distribution | Pattern Repetition |
| Complexity Test | Linear Algebra | Compressibility |
