NIST SP 800-22 Validation Results

qiprng achieved a 98.4% pass rate across all 15 NIST SP 800-22 test categories, confirming its suitability for cryptographic applications.

​
Test Summary

The NIST SP 800-22 test suite is the gold standard for evaluating random number generators for cryptographic applications. Our implementation was tested with:
  • Sample Size: 1,000,000 bits per sequence
  • Number of Sequences: 100
  • Significance Level: α = 0.01
  • Pass Threshold: P-value > 0.01

Validation Data

​
Excellent Discriminants

The package includes pre-validated discriminants that have been tested for optimal performance and randomness quality: 
# Load excellent discriminants
discriminants <- load_excellent_discriminants()

# Use for high-quality generation
config <- create_excellent_prng_config()
createPRNG(config)
Discriminant data is stored in inst/extdata/excellent_discriminants.csv and includes:
  • Pre-computed discriminants with proven statistical properties
  • Validation scores across multiple test categories
  • Performance benchmarks for each discriminant

​
Reproducibility

All validation results can be reproduced using: 
# Run complete NIST validation suite
results <- validate_qiprng_framework(
  test_categories = "all",
  nist_tests = TRUE,
  sample_size = 1000000,
  num_sequences = 100
)

# Generate detailed report
generate_detailed_report(results, "validation_report.html")
