Method and system for providing digital certificate function in TEE

The invention discloses a method and a system for providing a digital certificate function in a TEE. The method comprises the following steps: sending a TA installation request message to a TAM server, and installing a TA in the TEE configured in a mobile terminal by the TAM server; sending a digital certificate personalization request to the TSM server, and receiving a digital certificate issuedby the TSM server; and after the personalization is completed, performing corresponding processing on the received data to be processed by the TA based on the digital certificate so as to provide corresponding services. According to the method and system of the invention, the requirements on hardware are lower, no module such as an SE chip module needs to be configured to the device, the data storage and algorithm operations are implemented in the TEE, and the user can interact with the user through the TUI to ensure the security required by the service, the convenience and ease of deploymentof digital certificate fun
