Abstract
Embodiments of the present disclosure include a method, a device, and a computer program product for verifying an Internet of Things (IoT) device. The method includes, in response to boot of a trusted platform module (TPM) simulator, establishing an environment similar to the TPM in a trusted execution environment (TEE) of the IoT device. The method further includes sending, by a direct anonymous attestation (DAA) simulator in the TEE, an access request to an application in the IoT device. In addition, the method further includes, in response to receiving a response received by the application from a cloud platform, executing, by the TPM simulator, verification for the IoT device. In some embodiments, required TPM security services are simulated in the TEE of IoT devices, thereby minimizing the exposure of user privacy information while completing the verification and ensuring the security of verification.
