Can anyone point me how can i do it? Also, Is there any program to test it ?

Thanks & Regards,

Hi Asma

could you provide more details about "side channel test".

In general supported features are described in linux documentation

on i.MX Software and Development Tools | NXP

Linux Manual describes how enable them.

Best regards
igor

Hi igorpadykov‌,

Sorry, I myself was not very clear on this. Now I have received a bit of more information. Basically I am looking for DES DPA test. This is the patch and test I found from my colleague which they used in bare metal few years ago. I tried to apply the patch in CAAM driver (caamalg.c) and seems it has been changed a lot, hence cannot apply it. I am looking for something more recent in this to help with DES DPA test.

Regards,

Asma

Hi Asma

I am afraid it is not supported in nxp bsps, seems most suitable option

is to develop it using Commercial Support and Engineering Services | NXP
