Problems solved by technology

[0004] The program hardening method provided in the prior art is usually a code obfuscation method such as adding flowery instructions in the program. However, this kind of hardening method often causes program expansion and wastes system resources; Among them, it is completed by the compiler installed in the developer terminal, so that the batch maintenance of the program hardening method cannot be realized, and the maintenance cost is high

Abstract

The invention discloses an application program security reinforcing method and device. The application program security reinforcing method comprises the following steps: extracting an executable filefrom a preset application file in an application program; analyzing the executable file to obtain a data segment and / or a link segment in the executable file; and performing encryption processing on the data segment and / or the link segment in the executable file. According to the scheme, the data segment and / or the link segment of the binary file are / is encrypted to reinforce the application program, so that the reverse difficulty of the application program is greatly improved, and reverse analysis of the application program is effectively prevented, and code expansion of the application program is not easily caused; and the implementation process is simple and flexible, and batch maintenance is easy, and the maintenance cost is low.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an application program security strengthening method and device. Background technique [0002] With the continuous development of science and technology and society, the number of various applications is also increasing rapidly. However, program reverse developers or program reverse products can easily crack and attack the application program by decompiling the application program, thereby threatening the security of the application program. [0003] At present, in order to prevent the reverse cracking of the application program, there are many products and methods for strengthening the application program in the prior art. However, the inventor found in the process of realizing the present invention that the above-mentioned way in the prior art has at least the following defects: [0004] The program hardening method provided in the prior art is usually a code obfuscation me...
