from AWS IoT expansion package, ST use secure element STSAFE-A110. ST also provides middleware and SBSFU etc to support secure boot and AWS secure communication. My question is how difficult of using other secure element ATECC608A?

I think using other secure element should feasible, but not sure how difficult it is.

As ST provides a set of tools like SBSFU etc middleware, may I know is that easy to change to support other secure element other than STFAFE-A110?

hello @jiangpen​ ,

the ATEC is not an ST device, we are not familiar with it. On a first glance it looks similar, but it has different means to secure the I2C channel, which could result in significant change.
