What is the method for a CEC1702 entropy source to combine a DRNG to provide a TRNG output?
  • A Deterministic Random Bit Generator (DRBG) requires post-processing on the True Random Number Generator (TRNG) output using procedures described in the NIST SP 800-90x documents.
  • Firmware algorithms and crypto hardware blocks in the CEC1702 use the TRNG output as a seed (for example, SHA or AES) to generate a true random number.
