2.2.2 Random Number Generator (RNG)
The TA010 device includes a high-quality cryptographic True Random Number Generator (TRNG) implemented according to the NIST standards SP 800-90A/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:
- NIST SP 800-90A: Certified as part of the NIST Cryptographic Algorithm Validation Program (CAVP) certification process (Hash DRBG CAVP Certification)
- NIST SP 800-90B: Certified as part of the NIST Entropy Source Validation (ESV) process (ESV Certificate #E194 - Operating Environment 59V02 A2)
- NIST SP 800-90C: Provides recommendations on the creation of random bit generators that include DRBG mechanisms, as specified in SP 800-90A, and use entropy sources, as specified in SP 800- 90B.
