Abstract: A TEE-based method to establish trusted and secure channel between the user and public cloud environment, an apparatus, a computer device, and a computer-readable storage medium are provided. After a TEE is started, a trusted measurement mechanism of the TEE is called to perform security measurement on an operation environment and an operation content of a computing node operated in the TEE, and a measurement result is sent to a trusted verification module. Relevant verification information is acquired from a remote verification server of the TEE, and the trusted verification module is controlled to verify the measurement result according to the relevant verification information. When it is confirmed that the operation environment of the computing node is credible and the operation content of the computing node is secure, a communication channel is established between the user and the computing node.
