Embodiment Construction

[0018] The technical scheme of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] The present invention is based on the research of Android mobile operating system and intelligent terminal network communication security, and combines the traditional firewall solutions to propose a network firewall design model under the platform. And a security mechanism for underlying packet filtering is proposed. The basic flow of the security mechanism is as follows:

[0020] 1. Android framework structure, network data packets, and data filtering algorithm research

[0021] 1. Android system architecture

[0022] The Android operating system consists of the following four levels from top to bottom:

[0023] Application layer, application framework layer, component library layer and virtual machine, Linux kernel layer. In the application layer: Android includes a set of core applications (coreapplications): Email client, SMS (sho...

Abstract

The invention relates to a computer operating system, and discloses an Android-system-based safety protection method. An Android-system-based mobile terminal is effectively protected from an external network attack. The method specifically comprises the following steps of: (a) writing a bottom-layer module according to a Linux2.6 core of Android, and reserving an interface for a java native interface (JNI) function to call; (b) writing the JNI function according to the specification of the JNI, calling a performance function of the bottom-layer module according to needs, and encapsulating the performance function; (c) compiling the performance function into a modular form by utilizing a compiler of the Android; (d) loading the compiled module into an Android system by using a debugging tool; and (e) writing a foreground user interface (UI) and a user processing program, and calling an interface provided by the loaded module. The method is applied to the safety protection of the Android-system-based mobile terminal.

Description

technical field [0001] The invention relates to a computer operating system, in particular to a security protection method based on an Android system. Background technique [0002] The Android mobile operating system is a Linux-based mobile operating system developed by Google in November 2007. It is a truly open mobile device development platform. It is precisely because of its open source that the threshold for third-party software developers has been lowered a lot, and Android has attracted the attention of many developers since it was just launched. Through its unique Dalvik virtual machine, the program runs more efficiently on the mobile phone. It is because of its free and open source that Android can not only be limited to mobile phones, but also to a wider range of tablets or other smart devices. Therefore, the prospect of Android application and development is unlimited. However, with the increasing demand of users to access the network through Android smart term...
