Abstract: A device and a method for authenticating an application in an execution environment in a trust zone are provided. The method includes executing a client application (CA) in a normal world, receiving, in the normal world, a request for receiving a service of a trusted application (TA) of a secure world from the CA, acquiring, when the request is received in the normal world, source information of the CA loaded in a memory of the device, acquiring, in the normal world, first hash information from the source information, providing, to the secure world, the first hash information together with signature information and a sub certificate included in the CA, and authenticating the CA based on the sub certificate and a root certificate of the TA in the secure world.

Abstract: A method and an apparatus for executing applications in a highest-priority-first order in the processor divided into a secure mode area and a non-secure mode area are provided. The method includes receiving a request to be processed in the non-secure mode domain from the application, determining an access permission level configured to a resource used for processing the request, determining, when the access permission level allows for access from the secure mode domain, a priority of the application, changing the access permission level to allow for access by the non-secure mode domain according to the priority of the application, and processing the request of the application using the resource in the non-secure mode domain.
