Embodiment Construction

[0052] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0053] A specific method and device for improving the difficulty of cracking Java software, a verification method and a verification device provided in the embodiments of the present application are described below with reference to the accompanying drawings.

[0054] like figure 1 As shown, a method for improving the difficulty of cracking Java software provided in the embodiment of the present application includes:

[0055] S101, add an AOP aspect class in t...

Abstract

The invention relates to a method and a device for improving cracking difficulty of Java software and a verification method and device, and the method comprises the steps: newly adding an AOP sectionclass in a source code of the Java software, and obtaining the newly added source code of the Java software; compiling the source code and packaging a compiling result into a first Jar file; carryingout code obfuscation on the first Jar file, packaging an obfuscation result into a second Jar file, obtaining first abstract information, and carrying out hard coding on the first abstract informationinto a tangent plane class; compiling the source code again and packaging a compiling result into a third Jar file; and performing code obfuscation on the third Jar file and packaging the third Jar file into a finally published Jar file. According to the invention, codes of a tamper-proof module can be automatically woven into a large number of service processing methods through a compiler, whether someone tampers a software copyright protection module or not after the software is published is recognized at multiple positions of the Java software, the code obfuscation technology is combined,the cracking workload and cracking difficulty of the Java software are greatly increased, and the copyright protection strength of the Java software is improved.

Description

technical field [0001] The invention belongs to the technical field of software copyright protection, and in particular relates to a method and device for improving the difficulty of cracking Java software, a verification method and a verification device. Background technique [0002] The binary files compiled by the Java program can be easily decompiled to obtain the source code, and the source code can be reverse engineered, or after the source code is obtained, the software copyright protection part can be modified and then compiled to crack the software. , which poses a challenge to the software copyright protection of Java programs, and a more effective method for protecting Java software is urgently needed. [0003] At present, the software copyright protection modules provided by many software developers often obtain computer fingerprint information based on one or more information such as the unique characteristic code information of the computer, such as the network...
