Abstract

The embodiment of the invention provides a system calling method and device. The method comprises the steps of receiving a system calling request of an application and then conducting authorization check on the system calling request, sending the system calling request carrying the authorization and a preset safety identifier of a safety check module which serve as a sender identifier to a core after passing authorization check, and conducting corresponding system calling after the core receives the system calling request and determines that the sender identifier of the received system calling request is consistent with a prestored safety identifier. According to the method and device, authorization check of the system calling request of the application is conducted in an application layer outside the core, authorization is set in the system calling request and the safety identifier is preset in the safety check module to be identified by the core, the code does not belong to open source codes and is not made public, and therefore system calling safety is improved greatly.

Description

technical field [0001] The present invention relates to the technical field of terminals, and in particular, the present invention relates to a system calling method and device. Background technique [0002] With the development of science and technology, smart terminals such as smartphones, tablets and e-readers have become widely popular. Operating systems based on the Linux kernel, such as Android, Tizen, Ubuntu, and FireFox, are installed in a large number of smart terminals. These operating systems are usually implemented on the basis of the Linux kernel by adding their respective designed framework layers. [0003] In an operating system based on the Linux kernel (hereinafter referred to as the operating system), the Linux kernel uniformly manages system resources, and the method for the application program of the application layer (hereinafter referred to as the application) to make a system call usually includes: the application sends a system call request to the ke...
