Research And Implementation Of Key Techniques Of Android Intelligent Terminal Dynamic Configuration System

With the development of science and technology,people's lives are becoming more intelligent.Intelligent terminals just like mobile phones are spreading widely.These equipment have brought great convenience to our life.However,along with the virus software,many intelligent terminals are under serious security risks.The personal privacy of the one who uses intelligent terminal faces a threat,and the security of information in the military is suffering the threat too,as well as the government and the company,even the country.Therefore,it is of great significance to monitor the security of intelligent terminals in real time.Paper regards Android intelligent terminal as the research object.In the research of Android system architecture,the kernel layer control access,network communication technology,It puts forward a solution for Android intelligent monitor terminal security,and Android intelligent terminal dynamic configuration system was implemented.According to the security policy issued and stored on the intelligent terminal,the system monitors the intelligent terminal in real time to ensure the security of the intelligent terminal.Thesis research mainly finished the following several aspects work: in the research of Android system architecture,the kernel layer control access,network communication technology,on the basis of designing the Android intelligent terminal dynamic configuration system framework;based on open Xposed source framework,using the hook technology,realized the dynamic hijacking of the Android framework layer API,the technology would not modify Android installation package,make application interface,to ensure the effective implementation of the secure proxy functions;A combination of data and text messages through the network has been used,the design has realized one kind of special instruction format data transmission,to ensure the reliability of data transmission at the same time,and the transfer process have less effect on the performance of the system;Based on the security design idea of Smack module,the Linux security module is optimized to realize the dynamic writing and persistent storage of security policy and effectively protect the security policy issued.By constructing the actual environment test,the Android intelligent terminal dynamic configuration system has a high detection rate for the malicious behaviors of remote control and privacy theft with obvious features.
