Abstract
Although cloud computing enables us to dynamically provide servers with the ability to address a wide range of needs, this paradigm also brings forth many new security challenges. The security of virtual machines (VM) is one of such critical challenges for cloud computing. However, existing techniques for VM security, such as Terra, tboot and TXT, mainly focus on the security of VM running environment. There is a lack of protection mechanism for VMs themselves in clouds. In this paper, we propose a trusted launch solution for virtual machines (TLVM), including four systematic mechanisms, image encryption, measurement, attestation and security-enhanced authentication, for protecting VMs in clouds. We also discuss a proof-of-concept implementation of our approach. Our experimental results demonstrate the feasibility of our solution to protect the whole launch process of a VM.
