Abstract

The invention discloses an SO file protection method and device and an android installation package reinforcement method and system. The SO file protection method includes the steps of writing a to-be-protected SO file in a shell procedure file as code data, and protecting the SO file in the shell procedure. According to the technical scheme, by adding a shell to the SO file and protecting the SO file, the multiple protection is achieved for the SO file, an important code of an android installation package is further stored in the SO file, the reinforcement protection is achieved for the android installation package with the protected SO file as a protection object, malicious programs can be effectively prevented from conducting disassembling analysis on the SO file, the security level of the content of the SO file is improved, and the safety level of the android installation package is improved.

Description

technical field [0001] The invention relates to the field of data security, in particular to a method and a device for protecting an SO file, and a method and system for strengthening an Android installation package. Background technique [0002] The Android platform has developed rapidly and has gradually become the most popular operating system for mobile terminals. Compared with other terminal operating systems, the open Android system provides application developers with more functional interfaces. These functional interfaces improve the system scalability, but also facilitates malware. Malware such as Trojan horses targeting the Android system can be stored in the Android installation package in a disguised manner, tricking users into installing and granting certain permissions, and then performing some specific actions in the background by abusing permissions, including stealing user privacy, defrauding tariffs, etc.; Not only that, for some normal Android system appl...
