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

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?

Regards

Aslam

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?

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-mcus/i-mx-rt1170-crossover-mcu-family-first-ghz-mcu-with-arm-cortex-m7-and-cortex-m4-cores:i.MX-RT1170 for more details.

Hope that helps,

Have a great day,
Kan

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&keywords=libtomcrypt&qid=1616992323&sr=8-1
