Research on Android Access Control Based on Isolation Mechanism

With the rapid development of the Internet, the application of Android system is more and more widely. But then the user's privacy leaks, malicious software attacks and hacking and other security issues have become increasingly serious. Android privilege mechanism is an important security protection mechanism of Android. But the current authority mechanism cannot be a good solution to the problem of improper access and the lack of protection of the core thus brings potential safety hazard. A three-tier Android safety protection safety guarantee system is designed to protect the security control subsystem, which is composed of the application layer, the virtual monitoring layer and the trusted root layer. It then uses the security control subsystem to control the other main parts of the Android system. Experiments show that the system can effectively block applications with sensitive permissions, and put it into the isolation zone, finally integrated hardware mechanism to ensure the security of Android system.
