Abstract

The invention relates to a reinforcement method and device for an executable file. The reinforcement method includes the following steps: acquiring an executable file code of an application program; compiling the executable file code of the application program into an assembly file; acquiring an assembly code corresponding to a preset code needing to be protected from the assembly file; and inserting an anti-decompiling code into a position before the assembly code. According to the reinforcement method and device for the executable file, the executable file code of the application program is compiled into the assembly file, and the anti-decompiling code into the position before the assembly code, the security of the application program is improved, and the situation that malicious commands are implanted into the application program can be avoided; and normal execution of a protection code cannot be affected.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method and device for strengthening executable files. Background technique [0002] With the development of network technology, applications that provide various services have emerged. Install the application program on the mobile terminal and use the application program to enjoy corresponding services, such as taxi-hailing software, install the taxi-hailing software on the mobile terminal, start and run the taxi-hailing software, enter the starting point and destination to generate the taxi-hailing information, and send the taxi-hailing software The taxi driver who receives the taxi information can respond and provide service. [0003] However, when the application is installed on the mobile terminal, it is easy for the decompilation tool to directly read the executable file (such as the so file) stored in the libs directory in the application installation package, modify ...
