Problems solved by technology

[0024] Theoretically, the execution of application software on computing devices cannot escape reverse engineering
The essence of software protection is to continuously increase the difficulty and time cost of reverse analysis and cracking, so that the attacker needs to pay more for obtaining valuable information than the benefit he can obtain
[0025] Software protection will bring additional software development costs, such as increased development difficulty, extended development time, etc.

Abstract

The invention mainly discloses a system and method for protecting application software in an Android system from reverse analysis and decryption. The method mainly comprises the following steps: increasing interfaces for a LiDalvik virtual machine and a Linux system library in the Android system, so that the Android has a capability of directly loading a DEX format file and an SO format file from a memory; storing a core code of the application software in an online server, encrypting and signing the core code, sending the core code to the application software installed at a client end; after receiving the core code, verifying the signature and decrypting the core code by the application software; storing a plaintext into the memory, and directly loading the plaintext into the system; invoking the code; and releasing the memory. The method greatly improves the difficulty in performing reverse analysis and decryption by an attacker, so that the safety of the Android application software can be effectively protected.

Description

technical field [0001] The invention relates to a computer software protection technology, in particular to a software anti-leakage and copyright protection system and method, a server and an intelligent terminal for an Android platform. Background technique [0002] At present, the Android operating system developed by Google is already the mobile smart terminal platform with the highest market share in the world. The number of Android application software continues to grow, and a good software sales model has been established. Like the traditional PC platform, the successful commercialization of Android application software has also triggered their reverse analysis and cracking. [0003] Reversing analysis of application software includes: [0004] 1. Analyze the executable code of the software by methods such as disassembly, decompilation, and debugging to understand the execution process and algorithm implementation of the code; [0005] 2. Analyze the configuration f...
