Abstract

The disclosure provides electronic equipment and a dynamic-library-file protection method and device. The method includes: verifying whether an application program is a target application program whenthe application program calls an interface function of a dynamic library file; setting a value of a state variable, which is in the dynamic library file and at least acts on the interface function, from a first value to a second value when it is verified that the application program is the target application program; and setting the interface function to a non-executable state when the state variable is the first value, and setting the interface function to an executable state when the state variable is the second value. The method can prevent that the dynamic library file is called by a non-target application program.

Description

technical field [0001] The present disclosure relates to the technical field of application software development, and in particular, relates to a dynamic library file protection method, a dynamic library file protection device, and electronic equipment using the dynamic library file protection device. Background technique [0002] A dynamic library file is a way to realize the concept of a shared function library. The dynamic link method enables the application to call functions that do not belong to its executable code. The executable code of this function is located in a dynamic library file. The dynamic library file can contain one or more compiled, linked and used Functions that process separate storage. [0003] Taking the Android system as an example, the developer of the dynamic library file can write the core implementation scheme in a dynamic library file so library (so format dynamic library file) for the application program to call, and the so library will be pac...
