Hi,
I have updated the plug and trust middleware nano package se050_sign to support curved secp256k1 and have tested it on an OM-SEC050ARD-C2 Ardino board connected to a Raspberry Pi. It works fine, but when I try it with a K81 connected to the SE050-C1 secure chip, it fails.
Thanks,
Sureshkumar R
Hi @krsuresh ,
I think you have to create the curve for secp256k1 in SE at first. Please kindly refer to Se05x_API_CreateCurve_secp256k1() for details.
Have a great day,
Kan

Hi @Kan_Li,
Thanks for the quick response.
I'm unable to get the driver code for Se05x_API_CreateCurve_secp256k1() instead used Se05x_API_CreateECCurve() to created kSE05x_ECCurve_Secp256k1 curve but still facing the same issue.
In nano package, I'm not seen any function call like CreateCruve but still it working.
Thanks,
Sureshkumar R
Hi @krsuresh ,
Such kind of function just needs to be run once, so maybe the OM-SE050ARD-E board has already run this code so it works well with the demo out of the nano package, my OM-SE050ARD-E also experienced with this issue.
Have a great day,
Kan
