Azure Sphere Device Authentication and Attestation Service

The Device Authentication and Attestation (DAA) service is the primary point of contact with the Azure Sphere Security Service for Azure Sphere devices to authenticate their identity, ensure the integrity and trust of the system software, and certify that they are running a trusted code base. In addition, the DAA service provides Azure Sphere devices with a device authentication certificate, which can be used in downstream authentication flows to services such as the Azure Device Provisioning Service or directly to an Azure IoT Hub.
