Abstract

The invention relates to an access control method and system, an SE access plug-in device and a terminal, and relates to the technical field of mobile communication. The method comprises the steps that an SE access plug-in of the terminal receives request information, sent by an SP, for accessing a small application program in an intelligent card; the SE access plug-in sends request information tothe small application program through a machine card interface of the terminal so that the small application program can determine whether SP access is allowed or not according to a first access control strategy, wherein the first access control strategy is stored in the small application program; and under the condition that the small application program allows the SP to access, the SE access plug-in allows the SP to access the small application program through the SE access plug-in. According to the technical scheme, the security of access control can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of mobile communication, and in particular to an access control method, an access control system, an SE (Secure Element, security unit) access plug-in device, a terminal, and a computer-readable storage medium. Background technique [0002] SIM (Subscriber Identification Module, Subscriber Identity Module) card and eSIM (Embedded-SIM, embedded SIM) card operator's SE can provide hardware-level financial-level secure storage and computing service capabilities. SE supports mobile phone APP (Application, application program) to access APPLET (small application program) on the smart card, thereby enhancing the security of APP access. [0003] In related technologies, in order to ensure that the APPs accessing the APPLET are legal, GPAC (Global Platform Access Control, Global Platform International Standard Organization Access Control) is used for access control. Contents of the invention [0004] The...
