The Safety Assessment Of Mobile Intelligent Terminal And The Realization On Android Platform

With the development of mobile communication technology and mobile internet technology, the subscriber number and the market size of mobile intelligent terminal grows swiftly. A mass of private information, accounts and passwords are stored in the mobile intelligent terminal. However, the security issue of mobile intelligent terminal sticks out as the subscriber number, function and service of mobile intelligent terminal grows. The market size of Android increases rapidly because the powerful features, abundant applications and great performance of Android which attracts the customers. Android is a mobile intelligent terminal operation system based on Linux kernel. The characteristic of open-sourcing makes the Android system vulnerable to viruses, rogue programs which lead to the leak of private information. Therefore, the safety of Android operation system becomes more important. In this context, the security evaluation of mobile intelligent terminal especially the Android terminal becomes more urgent. The research of security evaluation provides the theoretical basis for generating the safety strategies of mobile intelligent terminal. In this paper, based on the analysis of current security threats and security mechanism of mobile intelligent terminal, security evaluations frameworks and security evaluation methods of mobile intelligent terminal are formulated in order to assess the safety of mobile intelligent terminal. The main work is as follows:(1)A security evaluation method of mobile intelligent terminal based on graphs and AHP is proposed and used to assess the Android terminal.(2)The access mechanism of Android mobile intelligent terminal is evaluated based on the deep analysis of security mechanism of Android mobile intelligent terminal.(3)An evaluation method of safety audit on Android mobile intelligent terminal is proposed based on the analysis of log system of Android mobile terminal.(4)Data security of mobile intelligent terminal is evaluated.(5)Security evaluation tools about intelligent terminal are exploited based on the research. Automatic evaluation on mobile intelligent terminal is realized.
