【摘要】：随着智能手机逐步成为人们工作和生活不可或缺的随身设备,其安全性和用户隐私问题也越来越突出。为解决该问题,提出一种基于Linux容器技术的方法,在同一台手机设备上建立多个虚拟手机系统,使多个相互隔离的Android系统同时运行。为了使多个子系统共享同一台设备资源,提出了基于代理的设备虚拟化技术,并以手机的Radio设备为例实现了该技术。然后,在一个实现了的原型系统上的测试结果表明每个虚拟手机系统均可正常使用所有物理设备,说明该方法可有效地实现设备的虚拟化。最后,通过对多系统的数据隔离、系统资源开销的测试验证了该方法的可行性。由于各虚拟手机系统之间相互隔离、互不影响,因而很好地保护了用户数据的隐私。此外,即使某一个Android子系统出现运行故障或者被恶意攻击,其他子系统照样可以正常运行,从而提高了整个系统的安全性。同时,各子系统的应用和功能可以根据不同的应用场景和需求特别定制,可满足用户的个性化需求。
[Abstract]:With the smart phone gradually becoming an indispensable device for people to work and live, the security and privacy problems are becoming more and more prominent. In order to solve this problem, a method based on Linux container technology is proposed. In order to make many subsystems share the same device resource, a virtual mobile phone system based on agent is proposed. In order to set up several virtual mobile phone systems on the same mobile phone device and make many isolated Android systems run simultaneously, a new technology of device virtualization based on agent is proposed in this paper. Then, the test results on a prototype system show that every virtual mobile phone system can use all physical devices normally. This method can effectively realize the virtualization of devices. Finally, the feasibility of the method is verified by the data isolation of multi-system and the testing of system resource overhead. Therefore, the privacy of user data is well protected. In addition, even if one of the Android subsystems fails or is maliciously attacked, the other subsystems can still run normally, thus improving the security of the whole system. At the same time, The applications and functions of each subsystem can be customized according to different application scenarios and requirements, which can meet the individual needs of users.
