摘要

虚拟化技术是云计算的基础。单个物理主机上的多个虚拟机相互隔离。而隐蔽通道则打破了这种隔离，隐秘地泄露了敏感信息。在本文中，我们利用共享内存在Xen hypervisor上构造了一种经典的隐蔽时序通道，即开/关通道。然后对其比特率和传输精度进行了评估。结果表明，这种隐蔽通道对虚拟化技术是一种威胁。

Constructing the On/Off Covert Channel on Xen

Virtualization technology is the basis of cloud computing. Multiple virtual machines on a single physical host are isolated from each other. However, covert channel breaks the isolation and leaks sensitive information covertly. In this paper, we construct one type of classic covert timing channel, the on/off channel, on the Xen hyper visor using shared memory. And then we evaluate its bit rate and transmission accuracy. The results show that this type of covert channel is a threat to virtualization technology.
