A71CH user authentication

Hello everybody,

I've bought A71CH Arduino evaluation kit and it looks like a perfect fit for my IOT needs.

Only missing thing is that for certain use cases I want to protect private keys with PIN or password.

Looking through documentation and samples source code, I could not find any such example.

Is such use case supported?

Or should I use another device, such as A700X, which is used in smartcards and certainly support PIN/PUK authentication?

Best regards,

A. Romanov

Hello Andrey,

On A71CH access to the keys (access means here usage, you anyway cannot read the keys) can be protected only by SCP03, while on SE050 you can use the different types of SCP + also PIN protection. Please refer to EdgeLock™ SE050: Plug & Trust Secure Element Family – Enhanced IoT security with maximum flexibility... for more details.

Hope that helps,

Have a great day,
Kan
