NRF52840 : mbdedtls with CC310 hardware-acceleration ?

[AKYR]

Hello Nordic team,

I'm currently looking into TLS on nRF52840, I'm using nRF SDK 15.3.0.

I have seend the DTLS example "nRF5v15.3.0\examples\iot\dtls\coap_client" that uses the external mbedtls library for both TLS and the crypto algorithms.

Then I looked into the nrf_crypto library and figured out that most algorithms can be hardware-accelerated with the CC310 cell using this cryptography library. 

So I was wondering if you had some kind of project/example that implements the mbedtls library with hardware-acceleration from the CC310 cell when possible or if I should do it by myself ? 

Thanks in advance,

AKYR

Hi,

There is no support for using CC310 to accelerate mbed TLS in the nRF5 SDK. The closest you get is the nrf_cc310_mbedcrypto library, but it is not very mature. Also, it is integrated with the nRF Connect SDK (which is used for nRF91), and not the nRF5 SDK.
