Security protection system and method for application program

Abstract

The invention discloses a security protection system and method for an application program. The security protection system comprises: an extraction module which is suitable for extracting a binary file from an application installation package, a check value generation module which is suitable for generating a check value according to the information corresponding to the specific position in the binary file, a specific data determining module which is suitable for determining various specific types of data contained in the non-code segment, an encryption module which is suitable for performingencryption processing on the check value and the specific type of data, a comparison module which is suitable for obtaining information corresponding to a specific position in the current applicationprogram when the application program runs and comparing the information corresponding to the specific position in the current application program with the verification value, and an attack determination module which is suitable for determining whether the application program is attacked or not according to the comparison result. According to the scheme, static analysis and dynamic analysis of theapplication program can be prevented, so that security protection of the application program is realized; and the implementation process is simple and flexible, and batch maintenance is easy, and themaintenance cost is low.

Description

technical field [0001] The invention relates to the field of computers, in particular to an application program security protection system and method. 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 and debugging the application program, thereby threatening the security of the application program. [0003] At present, in order to prevent reverse cracking and attacks on application programs, there are many products and methods for security protection of application programs 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 security precautions provided in the prior art are usually code...

AI Technical Summary

Problems solved by technology

[0004] The program security precautions provided in the prior art are usually code obfuscation methods such as adding flowery instructions in the program. However, this reinforcement method often causes program expansion, wastes system resources, and cannot accurately monitor the attacks on the application program; and , the existing program security protection method is completed by the compiler installed in the developer terminal during the compilation process, so that the batch maintenance of the program reinforcement method cannot be realized, and the maintenance cost is high
