Hi,

 

We have referred i.MX8MDual Processors datasheet.

Link: https://www.nxp.com/docs/en/data-sheet/IMX8MDQLQIEC.pdf 

 

In this datasheet,  Table No 3:

 

 

CAAM Section: CAAM is a cryptographic accelerator and assurance module. CAAM implements several encryptions and hashing functions, a run-time integrity checker, entropy source generator, and a Pseudo-Random Number Generator (PRNG). The PRNG is certifiable by the Cryptographic Algorithm Validation Program (CAVP) of the National Institute of Standards and Technology (NIST). CAAM also implements a Secure Memory mechanism. In i.MX 8M Dual / 8M QuadLite / 8M Quad processors, the secure memory provided is 32 KB

 

We need TRNG support in i.MX8MDual Processor. 

So, here the question is CAAM uses the TRNG for generating the random number? 

 

Please respond as soon as possible.
