面向BYOD的流式移动应用分发系统

在目前BYOD解决方案实现方式中，程序、数据全部存储在移动设备中，安全保障主要依赖移动设备上复杂的访问控制；同时现有方案不能充分利用移动设备的位置信息进行权限管理。针对上述问题，结合应用流式的思想，设计并实现了一个流式移动应用分发系统——AS-Droid。其拥有基于位置信息进行灵活的应用授权、管理的能力，并且使用轻量级客户端。实验结果表明，系统在BYOD下具备可用性，健壮性及安全性。进一步实验数据表明，在应用下载、安装及启动过程中，AS-Droid系统比Android系统能够减少超过35%的时延及大约25%的流量消耗，同时两种系统能耗基本持平。

BYOD oriented mobile streaming application distributing system

Currently, among the solutions of BYOD, applications and data are stored in mobile devices, whose security mainly relies on complicated access control. Besides, those solutions cannot make full use of the location information of mobile devices for authorization. In order to solve the above problems, referring to the idea “application streaming”, it designs and implements a system to manage and distribute streaming mobile applications ——AS-Droid. It is lightweight and can flexibly manage and authorize apps based on location. Experimental results show that the system is practicable, robust and secure enough under BYOD. In addition, it reduces more than 35% of time and about 25% of network traffic cost during application download, installation and startup and consumes roughly the same energy compared with Android.
