NIST SP 800-90B defines design principles, requirements, and validation tests for entropy sources used in random bit generation.
Strong cryptography depends on strong randomness. Entropy sources must be measured, tested, and validated before being trusted for keys, tokens, nonces, and secure systems.
This is one of the most important technical references for Light Rider’s Entropy-as-a-Service platform, Quantum Light devices, and QRNG-based security products.
