A secure and trusted execution environment is a fundamental requirement for distributed network, so that the integrity of service provider platform should be verified prior to services' distribution in order to assure that the platform is free from a malicious modification and attack. In this paper, we proposed an implementation of trusted execution environment based on the combination of trusted...
Virtualization has been widely used in cloud computing systems to cut costs, and to provide dynamically scalable resources over the internet. Many ideas have been proposed to increase the security of the virtualized systems. But, a big unspoken assumption of these ideas is that the cloud users have to trust the cloud provider totally and unconditionally. In reality, however, this assumption can't...
Trusted computing has been introduced into virtualization as an approach of providing trust in a computing platform. However, the primitive design of privileged domain menaces virtual TPMs with oversize of trusted computing base, leading to security vulnerabilities. This paper proposes a new administrative domain (Domain A), an architecture that prevents virtual TPMs from tampers. We port the VTPM...
We argued that virtual machine monitor (VMM) is the appropriate architecture for implementing TCG specification With analysis of limitations Trusted Computing Group (TCG) has encountered. Putting together the VMM architecture, TCG hardware and application-oriented ldquothinrdquo virtual machine (VM), Trusted VMM-based security architecture is present in this paper with the character of reduced and...
We present the design of a trusted platform module (TPM) that supports hardware-based virtualization techniques. Our approach enables multiple virtual machines to use the complete power of a hardware TPM by providing for every virtual machine (VM) the illusion that it has its own hardware TPM. For this purpose, we introduce an additional privilege level that is only used by a virtual machine monitor...
