Research On Analysis Method Of Mobile Application Defect

With the rapid development of mobile Internet technology and the popularity of intelligent terminals,intelligent terminal plays a more important role in people's life and work.It is more convenient for people to use intelligent terminals to do online shopping,mobile phone payment,video chat and other activities.Due to the openness of the Android System,Android intelligent terminal bring a big convenience to the users,but also brings a variety of security issues,such as privacy?consumption rates?system damage.As a result,these problems not only damage the user's economic interests,but also threat to the user's personal privacy and security.For security issues of the Android platform application software,the existing research is mainly to do analysis on a single application,using static or dynamic technology to detect the application of safety defects.As is known to all,the defect is ubiquitous.It is very limited to detect the security flaws only,without giving the trigger condition and protection method of mobile intelligent terminal.Firstly,this paper proposes a method of security flaw analysis for Android application software.The method uses static detection technology combined with defect rules to meet the needs of the Android defect detection.This method established defective triggering model for each category of application,which breaking through the limit of the traditional method of modeling the defect itself.Secondly,this paper designs the corresponding detection system based on this method.And then,the designed system has carried on the actual development and deployment.Furthermore,a large amount of data has been used for the test and verification of the system.The main work in this paper is as follows:(1)The paper studies on the Android platform security at present.This paperintroduced the research status of defect detection technology of the Android platform application,and conducted the thorough research on the Android system architecture and security mechanism.(2)Proposes a defect analysis method for Android application,and describes its process flow.This paper analysis this issue from both the defect detection and defect trigger perspective,introduced the application defect detection method,application defects trigger modeling methods and their respective works.(3)Studied the main technology of the Android application defect analysis,and provide a scheme of defect analysis system based on Android application software.And then,conducted a detailed module design and implementation of each subsystem.(4)The test flow and verification flow of the system are given.This paper take several experiments to test the system.Bythe system running process to test the function of each system module which verify the availability of the system;By has publicly vulnerabilities and attack methods to verify the analysis results show the effectiveness of the system.
