Is it possible do elliptical curve operation like ec add , ec mul on SE050

[mohamedaslam_m]

Hi team,

    we want to do some elliptical curve operations like EC addition and EC multiplication for our project. We are using SE050 as a cryptographic engine. Is those operations are possible to achieve using SE050?

Hi @mohamedaslam_m ,

I am sorry, but SE050 doesn't support EC calculation, it can just be used for EC curve management as well as writing or updating an EC key based on one of these EC curves.

Have a great day,
Kan

Hi Kan_Li,

   Thanks for the feedback kanLi. I am a bit stuck with this operation, could you please suggest any crypto library or any reference code, to achieve elliptical curve arithmetic operations from a microcontroller?

Sorry for the late answer, I don't read this regularly.  Try  libtomcrypt - the EC math stuff is under https://github.com/libtom/libtomcrypt/tree/develop/src/pk/ecc.

A manual for this is at https://www.amazon.com/LibTomCrypt-Developer-Manual-Tom-Denis/dp/B005D3VSRS/ref=sr_1_1?dchild=1&keyw...

Hi @mohamedaslam_m ,

Actually I have no idea of the crypto library or any reference code, but as far as I know, such kind of function is hardware supported in RT1170, please kindly refer to https://www.nxp.com/products/processors-and-microcontrollers/arm-microcontrollers/i-mx-rt-crossover-... for more details.

Hope that helps,

Have a great day,
Kan
