Abstract

The invention discloses an access control method and system for a security application. The method comprises the following steps: receiving an access request initiated by a source application in a common environment for accessing the security application in a trusted environment; sending the access request to a policy server, so that the policy server verifies the access request according to a pre-configured access rule; when the verification is passed, receiving an access request sent by the strategy server and signed by the private key; and sending the signed access request to an authentication and distribution program in the trusted environment, so that the authentication and distribution program sends the access request passing the authentication to a target application, and the targetapplication is a security application in the trusted environment corresponding to the access request. According to the invention, the security of the security application in the trusted environment can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to an access control method and system for security applications. Background technique [0002] With the rapid development of mobile communication technologies, mobile terminal devices are also widely used in various scenarios. [0003] Currently, systems of mobile terminal equipment are divided into REE (Rich Execution Environment, common environment) and TEE (Trusted Execution Environment, trusted environment). [0004] If the access control of the TA (Trusted Application, security application) in the TEE is not added to the mobile terminal device, the application in the REE can access the TA in the TEE at will, which will expose many risks, such as tampering or even leakage of the data safely stored in the TEE. [0005] Therefore, how to control the access of secure applications in trusted environments to improve the security of secure applications in trusted envi...
