Problems solved by technology

[0007] However, in the same processor, the time-sharing operation is used to switch the normal mode and the safe mode. In order to ensure safety, the switching between the two involves a lot of site protection and recovery work, so the efficiency of processing tasks is relatively low, and the task processing of the two working modes are based on the same processor, and its processing is not completely isolated, and operations in normal mode and safe mode may be affected by each other

Abstract

The invention relates to a mobile terminal and its processor system, and a trusted execution method. The processor system includes: an application processor configured to run an open operating system and execute tasks based on common application programs of the open operating system; a baseband processor configured to run a secure operating system, Executing tasks of trusted applications based on the secure operating system. The invention can improve the task processing efficiency in the process of switching the normal mode and the safe mode of the mobile terminal.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a mobile terminal and its processor system, and a trusted execution method. Background technique [0002] With the popularization of mobile Internet, the security problem of mobile terminals needs to be solved urgently. [0003] From the perspective of service types of mobile terminals, mobile terminals are gradually evolving into handheld terminal devices that integrate services such as plate call services, data services, information acquisition, electronic payment, and digital rights management (DRM). In a normal operating environment, the operating system of the mobile terminal is open, and the system and applications of the mobile terminal face a series of security issues. Based on the openness of its operating system, mobile terminals will inevitably run malicious software such as viruses and Trojan horses. Therefore, it has always been an important content to introduce a saf...
