The Raspberry Pi 4 model B can also implement a FIPS-compliant entropy source in the form of CPU Jitter Random Number Generator (JEnt)! It is listed under certificate E21 within NIST’s Entropy Source Validation Program (ESV), so it could even be used in a cryptographic module. ESV testing for JEnt uses an oversampling rate of 3, so even if you don’t want to use the precise setup described in the certificate (maybe a different version of OS, etc), the entropy rate from this will be more than adequate. |
