Digital True Random Number Generator


Random number generation is a keystone in security.

Secure-IC Security IP Digital TRNG

Secure-IC offers both True Random Number Generator (TRNG) resilient to harmonic injection for statistically independent sets of bits generation and Deterministic Random Bit Generator (DRBG) for high bitrates requirements.These random generators are compliant with commonly used statistical tests suites.

Secure-IC offers TRNG compliant with SP 800-90C.
