The Research And Implementation Of The Safety Testing System Based Onandroid Smart Phones

As function and computing power increased greatly , Smartphones represented by the most important mobile computing devices will become more and more important in people's life, work and study and finally gain popularity. Mobile computing devices are more easily lost, and personal information concerning the characteristics of its information security put forward higher requirements.Google's Android as the fastest-growing mobile operating system, Because of its natural systems inherited some of the advantages Linux has better system security, but the information in the application layer security mechanisms and the technology was not perfect, its security has become a serious problem to be solved. Construct a safety inspection system that based on Android smartphone also becomes more important and urgent.Through research and analysis Android platform structure and the special nature of security threats, combined with the essence of traditional PC security detection technology and the latest safety testing ideas, this paper from the static and dynamic two different levels to build the safety inspection system for smartphones based on the Android platform. The main contents of this paper and the results are as follows:First of all, this paper analyze the security status of smart phones, then Through research-based Android platform to analyze the security elements and requirements of its security features, and research based on the analysis of the appropriate safety testing technology, by learning and improving ideological and traditional security detection technology, from two different levels of static and dynamic design Android platform-based security detection systems.Secondly, from a static point of view, Based on the Android platform with an application to extract signature features, and in the traditional static methods of detection and by adding the heuristic information, thus to improve the detection ability, while taking the static testing of logic and intelligent to improve the detection of the flexibility of the module..Then, Using the framework of the platform characteristics and design principles based on linux kernel to monitor and test the key security elements of the system operation.Finally, By analyzing the Android platform application at run time the behavior shown by state transition diagram, and tap the state transition diagram contains the behavior patterns of behavior behind the application ,then by extracting the corresponding changes in the the system, built security detection model on the HMM-based recognition principle to detect applications and components the existence of abnormal behavior .
