CSEc Random Number Generator standard

Architecture was S32K146. According to the AN5401.pdf, Random Number Generator standard is:

1.1 CSEc security module features

• True & Pseudo random number generation

Above, we project need the Random Number Generator standard choose any one of A ,B, or C:

A The random number shall be generated with a AIS31 Class P2 compliant generator.
B ・The random number shall be generated with a AIS20 Class K3 compliant generator.
・Input value (SEED) shall be generated with random number generator complying with AIS31 ClassP1 and more.
C The random number shall be generated with a NIST SP800-90 compliant generator.

So,could you tell me the CSEc‘s random number generator (RNG) standard satisfies A or B or C?

Hi @Gideon

TRNG meets requirements given by standards SP800-90B and AIS31 (class PTG.2). PRNG is consistent with the requirements of the predefined class DRG.2 in AIS31.
I can share a document with more details but it is available only under NDA. If you want to get the document, please submit a ticket here:
