Crypto Cell 310 dev on nRF9160 (zephyr)

[Bhavya]

Hi all,

I am using ncs version 1.5.0 and dk version 0.15.0.

I would like to rely on the CC310 piece of hardware to perform some cryptographic computation.

However, I haven't been able to find any sample code or documentation regarding interfaces, API to use.

Can someone help me, point me out some hints to start using CC310 ?

Thanks in advance

Hi,

You can use the nrf_cc3xx_platform library after initializing the CC310 hardware driver. You can refer to the crypto tests to see how it can be used. Note that CC310 can only be used in secure mode, so if you want to use it from non-secure you need to either implement a secure service for it or alternatively use TFM instead. This is not yet mature, but will be the preferred way to use CryptoCell on nRF91 or nRF53 going forward. See TF-M hello World for a simple sample of that.
