Integrating system-level virtualization technology with Trusted Computing technology can significantly improve system security. The open-source virtual TPM facility, shipped with the open-source hyper visor Xen, aims to provide the illusion of a physical TPM to TPM-based trusted software executed in trusted virtual machines (TVMs) such that TPM-based trusted software works well in a TVM as in a native...
We introduce a model for secure managing virtual infrastructure in IaaS Cloud which called Trusted Private Virtual Data center (TVPDc). It can offer centralized management of the computing and storage resources distributed in different locations and physical machines within an IaaS cloud. Additionally, we propose a hierarchical management framework and a TVPDc establishment and deployment protocol...
A key technology of cloud computing is virtualization, which can lead to reduce the total cost and increase the application flexibility. However along with these benefits come added security challenges. The extension of Trusted Computing to virtual environments can provide secure storage and ensure system integrity. In this paper, we describe and analyze several existing virtualization of TPM (vTPM)...
Cloud computing enables organizations to realize the commercial benefits while facing the new security issues. In this paper, we presents a security model for called the Trusted Private Virtual Data center (TVPDc) that offering centralized security management of the computing and storage resources distributed in different locations and physical machines within an IaaS cloud. The TVPDc model can satisfy...
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...
