In order to enhance the security of Android applications,we propose a repackaging and dynamic authority management scheme based on Android application reinforcement methods.Instead of using root privileges and system modification,we introduce a user-level sandbox,which utilizes the native C-level interception mechanism,to further reinforce the risk applications and improve the entire security of Android system.Additionally,by importing and improving the repackaging features,this proposed scheme reduces the potential risks of applications and achieves the goal of the dynamic monitoring of permissions.Finally,a comprehensive evaluation,including efficiency analysis and detection evaluation with 1 000 malwares,whose overall average success rate is about 96%,shows the feasibility and universality of the proposed scheme.

Additionally, by importing and improving the repackaging features, this proposed scheme reduces the potential risks of applications and achieves the goal of the dynamic monitoring of permissions. Innally, a comprehensive evaluation, including efficiency analysis and detection evaluation with 1 000 malwares, whose overall average success rate is about 96%, shows the feasibility and universality of the proposed scheme.
