Conceptually, the ATECC508A-AWS communicates with the TLS stack in the system to protect IP based communications. It handles all asymmetric keys, cryptographic, and certificate manipulation to remove the keys to the software stacks to ensure they are never exposed. The injection of the keys and certificate is during the manufacturing process at Microchip factories. Various TSL stack options are available such as WolfSSL, OpenSSL, CycloneSSL, as well as the integrated TLS stack of the WINC1500 Microchip Wi-Fi.
