智能手机安全防护系统开发研究

The Development of Security System of Smartphone

从本机安全、手机网络安全、短信和来电安全三个方面进行智能手机防护系统开发。本机安全防护,通过采用二次随机特征提取法构建自己的病毒样本特征库,进行病毒样本扫描,开发一些系统管理工具;网络安全防护,通过SPI对无线网络数据包分析,实现Web、WAP恶意网址过滤、监控未知进程联网动作、监控网络流量;短信和来电,通过对于号码和数据的双重分析,以统计的思想作为基础,实现了短信的过滤,通过对手机抽象线路的监控,实现来电的过滤。

A smartphone security system is designed from three sides,which is local security,network monitoring,management of message and call.Local security is based on the analysis and scan of samples of the virus and network monitoring is to analyze the wireless data packet with SPI to filter the malicious website.The management of message and call is to filter some message and call through the analysis of telephone call number and the content.
