6.1 Use Cases

The ATECC608B-TNGTLS has been defined to specifically address the IoT market. Through a single set of certificates, the device has been set to directly support the Google IoT Cloud™, Amazon Web Services (AWS®) and the Microsoft® Azure Cloud. For other IoT networks or for any Public Key Infrastructure (PKI), custom certificates may be required and the customer should consider using Microchip’s TrustFLEX family of devices. A brief description of the primary use case for this device is provided below.

Secure TLS Connection

The ATECC608B-TNGTLS allows the creation of secure TLS connections using a variety of protocols. The device is capable of establishing secure connections to the Google Cloud, to AWS and other cloud providers. Through the various modes of the Key Derivation Function (KDF), appropriate keys can be generated to support TLS1.2, TLS1.3 and earlier secure connection internet protocols.
