Trusted Storage Virtualization in Cloud Computing

Abstract

The IaaS cloud computing is utilized by companies to gain benefits in reducing their IT expenses and overhead. However, in reality, it is rarely done because of security concerns, especially storage security of insider attacks. To reduce the risk of insider attacks, this paper presents a trusted Virtual Block Store (tVBS) architecture in IaaS cloud computing based on virtualization and Trusted Computing technologies. The core component of the tVBS is the trusted virtual block device, which can be automatic deployed and be attested by customers. The tVBS makes the virtual block storage device like a trusted physical block device to customers and extends host TPM trust into the computing environments within all virtual block devices. We also have implemented a prototype of the tVBS architecture based on the Xen hypervisor.
