CC312 support on nRF5340

[korkikian]

I would like to know if Nordic has implemented software support for CryptoCell-312 (nRF5340) in the latest master branch?

Right now I am able to use mbedTLS "frontend", e.g. cipher_block_op(), but I am not sure about the "backend". It looks like that the backend for AES-128 is still software implementation.

To give you a bit of context, I need to perform a lot of AES-128 encryption/decryption and I would like to be as fast as possible for this task. I worked with nRF52840, where the CC310 was working fine, and now I would like to check on nRF5340.

Hi, 

We are working on support for CC312 but it is not available yet. 

I worked with nRF52840, where the CC310 was working fine, and now I would like to check on nRF5340.

arm-cryptocell-cc310-backend only support nRF52840 and nRF9160 now. 

Please note that we are moving into the summer vacation period here in Norway, so it might take a bit longer to get to the bottom of this than expected, as staff during the month of July will be reduced. I'm sorry about the inconvenience, but please be patient. And I'll get back to you as soon as I hear something from the devs.

Thank you very much!

I will monitor the master branch to see if the support is implemented, but could you, please, update this thread once the support is implemented. In that case everyone will know that nRF5340 has software support for CC-312.
