Digital True Random Number Generator


Random number generation is a keystone in security.

Secure-IC offers both True Random Number Generator (TRNG) resilient to harmoni c 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.

  • TRNG
