Remote attestation

An electronic device, comprising a memory, a processor, and a computer program stored on the memory and executable on the processor, wherein the processor, when executing the program, implements operations comprising:

• initiating, by a first application, a remote attestation request to a second application, wherein the second application runs in a second trusted execution environment, and the first application runs in a first trusted execution environment;
• obtaining a first attestation response returned by the second application;
• obtaining a first attestation evidence of the second application from a target trusted storage module, wherein the first attestation evidence is uploaded and stored in the target trusted storage module by the second application;
• and
• performing remote attestation based on the first attestation response and the first attestation evidence, to obtain a first remote attestation result for the second application.

A non-transitory computer-readable storage medium storing computer instructions, wherein the computer instructions are configured to cause a computer to execute a remote attestation method comprising:

• initiating, by a first application, a remote attestation request to a second application, wherein the second application runs in a second trusted execution environment, and the first application runs in a first trusted execution environment;
• obtaining a first attestation response returned by the second application;
• obtaining a first attestation evidence of the second application from a target trusted storage module, wherein the first attestation evidence is uploaded and stored in the target trusted storage module by the second application;
• and
• performing remote attestation based on the first attestation response and the first attestation evidence, to obtain a first remote attestation result for the second application.
