Abstract
Cloud computing bring a tremendous complexity to information security. Many researches have been done to establish and maintain the trust relationship in cloud. Remote attestation is one of the most important feature of trusted computing. But conventional ways of remote attestation can only attest to the presence of a particular binary. They cannot measure program behavior. Existing dynamic remote attestation technologies can solve some of these problems. But they are not suitable for cloud computing when users lose their control over their critical data and business processes. In our opinion, cloud should give controls back to the users at some extent. So we propose TBVMM, a novel mechanism for cloud computing to fill the trust gap between the infrastructure and upper software stacks. TBVMM will pave a way for establishing better trust relationships in cloud environments.
