| 摘 要： | 针对Windows进程的冷冻与解冻问题，提出一种内核级的解决方案。基于Windows研究内核，给出进程冷冻和解冻的架构，完整保存进程内存映像，实现冷冻进程的自解冻。对于已打开多个文件句柄的进程冷冻情形，通过在内核进程对象中事先预留文件句柄的方法，使进程解冻后成功恢复文件句柄和数据。通过2个典型实验结果证明了该方案的正确性。

| Abstract: | This paper presents a kernel-level solution for the freezing and unfreezing of process on Windows platform. Based on Windows Research Kernel(WRK), it describes a whole skeleton of process freezing, which saves full image of process and support to self-unfreezing. For the process with multi-file handles, by reserving the file handles in process object of kernel ahead, the unfreezing process restores these file handles and corresponding data. Two typical experiments show the way is correct. |
