I am using a third party chriptographic engine that provides a dedicated hardware accelerator for AES-128 encryption based algorithms.
I am using this engine to encrypt the data transmitted and received over RF. To make the data more secure I am looking at generating encryption 128-bits keys using a True Random Number Generator. Is there a way of achieving a true random number generation using nRF5340 or Zephyr?
There's a separate peripheral block that generates random numbers: https://infocenter.nordicsemi.com/topic/ps_nrf5340/rng.html
