Check out how to improve IoT security by securing the authentication between Google Cloud IoT core and IoT devices using a secure element (ATECC608A) from Microchip.
In this use case, we illustrate how the ATECC608A combined with Google Cloud IoT Core from Google Cloud Platform enables secure authentication. The philosophy with secure elements in IoT is to provide a unique, trusted and protected identity. To achieve the objective, the identity provisioned to the hardware must be genuine and the cloud platform needs to be able to trust it. Consequently, a chain of trust must be created.
