1.2.2 Random Number Generator

The ATECC608B includes an enhanced high-quality cryptographic RNG, implemented by using a combination of non-deterministic noise (entropy) source (NRBG) and seeding a deterministic algorithm (DRBG) implemented according to the National Institute of Standards and Technology (NIST) standards. The NRBG is used in the instantiation and each time an RNG number is required.
