英文摘要	Covert channel between virtual machines is one of serious threats to cloud computing, since it will break the isolation of guest OSs. Even if a lot of work has been done to resist covert channels, new covert channels still emerge in various manners. In this paper, we introduce event channel mechanism in detail. Then we develop a covert channel called CCECS(Covert Channel using Event Channel State) and implement it on Xen hypervisor. Finally we quantitatively evaluate CCECS and discuss the possible mitigation methods. Results show that it can achieve larger bit rate than most existing covert channels. ?
