Design And Implementation Of VoIP System Based On Android

With the rapid development of mobile Internet,mobile equipment security issues have become more and more attention.The Android operating system is open and open source.There is a lot of Android applications.They involve all aspects of daily life.There are many security issues in Android applications.The Android vulnerability is the biggest.For the Android vulnerability security problems of Android applications,this article analyzes the Android vulnerability and form a vulnerability rule library.An online Android APP vulnerability detection system has been designed and implemented in this paper.Our work is summarized as follows:Firstly,this thesis conducts a meticulous study on the Android system architecture,dalvik instruction set and dex file format.We present the method of Android vulnerability detection including static analysis and dynamic analysis.Meanwhile,this paper describe the common vulnerabilities of Android application in details,including the condition,scope and strategies of vulnerability.On that basis,we mainly research the design of Android APP vulnerability detection platform.This paper introduces the overall architecture and the web service function module of the platform.At the same time,we also describe the static analysis module and dynamic analysis module of the local APK file vulnerability detection system.Finally,we introduce the implementation process of the Android APP vulnerability detection platform in detail.We focus on describe the implementation of web server and local system.The performance of the Android APP vulnerability is evaluated by test cases.And the test results have achieved a great fruition.
