Nordic security module port as SES project ?

[AKYR]

Hello Nordic team,

I'm currently developping a project that uses the nrf52840 as an HTTP server/client on top of its Bluetooth functionnalities. 

I'm looking into implementing the Transport Layer Security (TLS) using the CC310 crypto-cell to lighten CPU charge.

I've read the documentation about the Nordic Security Module, from nrfxlib git repository : https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/nrf_security/doc/nrf_security.html

It looks like the perfect module for my needs but my entire project uses Segger Embedded Studio organisation in the same way the nRF5 SDK v15.3.0 examples do.

Questions: 

Do you have an example for the Nordic Security Module for Segger Embedded Studio ? 

If not do you have any tips on how to add the CMake example from https://github.com/NordicPlayground/nrfxlib/tree/master/nrf_security into an existing Segger project ? 

Thanks in advance ! 

Aloïs KYROU.

This is not something we have ready, but I have asked the SDK team and here are the main pointers on how to build the crypto library in NCS and include it in nRF5 SDK:

• nrf_security must be enabled in an "empty project" in NCS
  
• Once configured and built the libraries and headers must be copied from the zephyr folder. There are some scripts to facilitate combining the libraries for a better convenience here:

https://github.com/KaSroka/fw-nrfconnect-nrf/commits/ot-crypto-lib-build

• • Check the last two commits. It should be good enough to understand what to copy from the build directory. extract_libs.sh and update_libs.sh (They are very OpenThread centric and some paths are true only on my PC - some improvements are needed here, but should be helpful.)
    
• The configuration file (nrf-config.h) and the appropriate headers (generated_includes) must be used in the nRF5 SDK project
  
• Note: There is no need to set mutex-support for a nRF5 SDK usage unless you plan to run FreeRTOS

• • If the FreeRTOS integration is needed specific APIs to set the FreeRTOS mutexes must be called before initializing the library

Hello Kenneth,

Thanks for your answer. I'll look into it and come back later wih inputs about how it is going. 
At some point if you feel that it can be usefull I'll share my project :) 

So I keep the thread open so far,

Have a good day !
