AN12132 - A71CH for secure connection to OEM cloud

This document describes how the A71CH security IC can be used to establish a secure

connection between an IoT device and the OEM cloud. It introduces ECC cryptography

and SSL/TLS protocol fundamentals and for demonstration purposes, it describes step

by step how to initiate a TLS/SSL based communication using A71CH OpenSSL Engine

example scripts [OEM_CONNECTION].

AN12120 - A71CH for electronic anti-counterfeit protection

This document describes how A71CH can be used for proof-of-origin verification or

anticounterfeit protection. The document introduces ECC cryptography fundamentals, it

describes the mechanisms and credentials involved to perform a cryptographic mutual

authentication between a server and an IoT device. And finally, for A71CH evaluation

and demonstration purposes, it details how a mutual authentication can be performed

using the A71CH Configure tool, OpenSSL and A71CH OpenSSL Engine libraries

[A71CH_ANTICOUNTERFEIT].
