Abstract

The invention provides a method for anti-decompilation based on an Android resource file index table, comprising: acquiring an Android resource file index table; parsing the Android resource file index table, and abstracting the Android resource file index table into a program class according to a file structure description document; Modify the resource file index table according to the program class; repackage the modified resource file index table into an APK. The invention realizes the function of the APK against the decompilation tool, and can modify the content of the Android resource file index table without affecting the normal operation of the APK, so as to achieve the function of against the decompilation tool.

Description

technical field [0001] The invention belongs to the technical field of software security, and particularly relates to a method, system and device for resisting decompilation based on an Android resource file index table. Background technique [0002] With the popularization of mobile devices, the Android system (a free and open source operating system based on the Linux kernel) has been supported by many developers at home and abroad by virtue of its open source advantages. [0003] APK (Android application package, Android application package) is an installation package file of Android software. The APK can be opened by decompression, and the APK includes the programs, resources, signature information, etc. when the software is running. At present, APK is facing the situation of being cracked by software through illegal means. How to use technical means to improve the security of APK and protect the interests of users is an important issue faced by many Android applicatio...
