Android手机防火墙的设计与实现.docx

Android手机防火墙的设计与实现摘要伴随着移动技术的发展，尤其计算机无线通信技术在手机等移动终端中运用的日趋成熟，手机已经发展成通讯、娱乐、办公等集多功能于一体的便携式设备。但随着智能手机的普及，手机安全问题也日渐严重。诈骗、广告、房产中介等等骚扰电话和短信影响了用户使用体验。更有甚者，针对手机开发的木马程序威胁着用户的隐私安全。因此为移动终端设备安装防火墙就成为保障移动终端安全的重要措施。本文主要研究了如何设计开发安卓智能手机通话和短信的防火墙。内容包括：阐述了安卓手机防火墙研究的背景和意义，就国内外研究现状进行对比，介绍研究相关的技术理论。针对手机防火墙需要实现的功能进行需求分析。在设计部分重点研究了用贝叶斯分类算法和特征向量提取进行短线防火墙设计，利用安卓的AIDL机制进行来电防火墙设计。并给出了过滤、文本分类、短信监听来电监听和挂机功能的实现过程，最后测试防火墙是否实现了需求所提的功能。关键字: 移动终端,防火墙,智能手机,安卓ABSTRACTWith the development of mobile technology, especially computer technology in mobile phones and other wireless communications mobile terminal use matures, mobile phones have evolved into communication, entertainment, office and other set-in-one portable devices. Smartphone replace the laptop has become the current mainstream mobile terminal. But with the popularity of smart phones, mobile phone has become a serious security problem. Fraud, advertising, real estate agent, etc. harassing phone calls and text messages influenced the user experience. Moreover, for the handset development Trojans threaten users privacy. Therefore, install a firewall for mobile devices have become an important measure to protect the safety of mobile terminals.This paper studies how to design and develop Android smart phone call and SMS firewall. The main contents of this paper include: describes the background and significance of the Android phones firewall studies comparing the current research, introduce research-related technical theory. Firewall for mobile phones need to achieve functional requirements analysis. In the design section focuses on the use of Bayesian classification and feature extraction algorithms were short firewall design, using AIDL mechanism Andrews were calls firewall design. And gives the filtering, text classification, SMS monitor the implementation process monitor calls and hang up function, and finally test whether the firewall needs to achieve the proposed function.Keywords:mobile terminal, firewalls, Smartphone, Android绪论研究背景及意义互联网技术飞
