Is the TRNG on the next generation Kinetis K6x devices NIST compliant? This is for a medical company so security is critically important.

Hi,

I think K64/K65/K66 RNGA module is compliant with NIST.

There with below description from RNGA module chapter of related reference manual:

It is important to note there is no known cryptographic proof showing this is a secure method of generating random data. In fact, there may be an attack against this random number generator if its output is used directly in a cryptographic application. The attack is based on the linearity of the internal shift registers. Therefore, it is highly recommended that this random data produced by this module be used as an entropy source to provide an input seed to a NIST-approved pseudo-random-number generator based on DES or SHA-1 and defined in NIST FIPS PUB 186-2 Appendix 3 and NIST FIPS PUB SP 800-90.

Wish it helps.


Have a great day,
Ma Hui
