Design And Implementation Of Android Security Protection And Optimization System

With the more and more important role of smart phones in people’s life,Androidplatform becomes the largest mobile operating system.But as the consequence ofincreasing popularity of Android platform,the number of malware aiming at it has beenincreasing,driven by huge business interests, which keeps threatening users’ interests andinformation safety.Although Android system provides lots of measure to protect customsystem, such as sandbox mechanism,Permission mechanism,autograph mechanismetc,serious threatening to security that has appeared in Android system,such as openmodel,system vulnerability,software vulnerability,Permission mechanism vulnerability,need external safety devices system to deal with safety threat that Android is facing.The paper attempt to design a system that could distinguish hostile attack,on thebasis of Android system,discover malicious attack and optimize resources.By analyzingthe system structure and safety mechanism of Android operating system,and starting fromits classical malware,the paper gives the Conclusion of malware’s attacking intentions andmeans in Android platform.Finally,according to overall consideration to the situations ofAndroid system itself and malware action model based on it,the paper realize the designof communication protection module with black or white list technology,key wordtechnology and text classification technology, design malware distinguish module withstatic checking and analysis,and reach the fanal goal of designing the Android securityoptimization and protection system composed by communication protection module,malware distinguishing module and dynamic protection module.
