3.2.2 Random Number Generator (RNG)

The ECC204-TFLXAUTH device includes a high-quality cryptographic True Random Number Generator (TRNG) implemented according to the NIST standards SP800-90A/B/C.

The NRBG output is evaluated using the methods in NIST SP 800-90B. The DRBG is designed using the SHA-256 variant specified within NIST SP 800-90A. The combination of the two creates the TRNG output following the methods specified in NIST SP 800-90C:
