【摘要】:為抵御Android系統(tǒng)的提權(quán)攻擊,避免應(yīng)用在權(quán)限傳遞的時(shí)候,造成威脅性的權(quán)限泄露,利用Fuzzy-IBE設(shè)計(jì)一種對(duì)權(quán)限進(jìn)行約束的權(quán)限管理模型。通過屬性對(duì)APK的核心模塊或者敏感資源進(jìn)行加密操作,使得在要訪問該APK的其余APK中,只有符合特定條件的APK,才能利用系統(tǒng)的私鑰恢復(fù)出數(shù)據(jù),訪問原APK應(yīng)用的資源和模塊。通過該模型,可以進(jìn)一步規(guī)劃系統(tǒng)資源,規(guī)劃某一APK應(yīng)用中敏感數(shù)據(jù)的訪問權(quán)限,優(yōu)化系統(tǒng)和應(yīng)用自身的模塊管理,有效避免提權(quán)攻擊。
[Abstract]:In order to resist the privilege attack of Android system and avoid the threatening authority leakage caused by the application of authority transfer, a privilege management model is designed by using Fuzzy-IBE to constrain the authority. The core module or sensitive resource of APK is encrypted by attribute, so that in the other APK to access the APK, only the APK, that meets the specific conditions can recover the data by using the private key of the system, and access the resources and modules of the original APK application. Through this model, the system resources can be further planned, the access authority of sensitive data in a APK application can be planned, the module management of the system and the application itself can be optimized, and the power attack can be effectively avoided.
