Remote Attestation is a mechanism to confirm the genuine device and software. This mechanism is required for IoT devices because they are geographically distributed without an administrator, especially on the IoT devices which treat confidential data. To run a confidential application, CPU has a TEE (Trusted Execution Mechanism). The most popular IoT CPU, Arm Cortex-A also have TEE mechanism named TrustZone.

I report on the attestation mechanism implemented in OP-TEE, a trusted OS running on the Arm Cortex-A TrustZone. This mechanism generates attestation evidence accepted by VERAISON, an open-source verification platform.

I report the provisioning process for both the attester and verifier in this model, emphasizing the need for secure setup. Additionally, we explain how to program a confidential application to leverage this remote attestation mechanism. These explanations aim to enable broader adoption of remote attestation by users.

The current source code is open and runs on QEMU and Raspberry Pi 3:

The source codes are integrated into the OP-TEE mainline:
