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.
