Abstract
Embodiments of the present invention relate to a trusted application access control method and a terminal. The method includes: receiving, by a terminal in a TEE, a request for accessing a target trusted application (TA) that is sent by a client application (CA); determining, by the terminal, a service level of the CA in a trusted execution environment (TEE) based on the request for accessing the target TA; and providing, by the terminal in the TEE by using the target TA, a service corresponding to the service level for the CA. In this way, the target TA provides different levels of services for the CA, and determines, in the TEE, the service level corresponding to the CA, thereby enhancing constraint and limitation of accessing the target TA by the CA, and improving security of accessing the target TA by the CA.
