摘　　要：针对虚拟桌面操作系统在遭受恶意攻击后灾难文件的检测和恢复问题,设计了基于Xen虚拟化技术的虚拟桌面操作系统引导文件和关键文件灾难恢复系统。该系统在离线状态下计算被检测镜像中引导文件和关键文件的特征码,将其与特权虚拟机中对应备份文件的特征码比对,对灾难文件进行精确定位,再使用备份文件进行快速恢复。实验结果表明,该系统能快速有效性的检测和恢复虚拟桌面操作系统灾难文件。To solve the problems of detecting and recovering disaster files which are maliciously attacked in the virtual desktop operating system, A disaster recovery system is designed for boot files and critical files based on Xen. The signatures of boot files and critical files of the images are calculated while the systerm is offline. By compared with the signatures of corresponding backup files in privilege virtual machine, the disaster files are located precisey and backup files are used to recoversed quickly. The results indicate that the system can quickly detect and effectively recover disaster files of Virtual Desktop Operating Systerr.
