Security in Virtualized Cloud Computing Environment

Virtualization technology has been widely adopted into cloud and enterprise computing environments. While virtualization can improve security in shared cloud infrastructures through greater isolation between virtual machines (VMs), and more transparent malware analysis and intrusion detection, it also gives rise to new privacy and security challenges. This project aims to advance the state-of-the-art in privacy-preserving and secure virtualization technologies such that users of a cloud infrastructure can expect tangible guarantees on the lifetime and accessibility of their confidential data.
