Hardware ECC

The "libbo_crypto" library demonstrates how to use mbedTLS for Elliptic Curves which I understand to be a software implementation.

However inside bps_defaults there is reference to "Elliptic Curve Controller | dg_configUSE_HW_ECC".

Is there example code for using these hardware elliptic curve routines? How much faster are these hardware routines?

Thanks.

Hi ddustin,

Hi ddustin,

We do not have any available example demonstrating how to use the hardware elliptic curve routines. Although, in DA1468x_DA15xxx_SDK_1.0.14.1081\sdk\interfaces\crypto path of SDK folder, you could find some implementations and APIs for creating Public Keys, ECDH etc. I would highly suggest you to read first the datasheet in order to understand how the ECC works.

Thanks, PM_Dialog

Thanks for the tip. When you say “I would highly suggest you to read first the data sheet” — which datasheet are you referring to?

Hi ddustin,

Hi ddustin,

I would recommend you to read the 14.0 ECC Engine paragraph of the DA14680 datasheet. You can download the datasheet and all the available documentation from our support portal.
