Cloud computing is a wide-spread technology that enables the enterprises to provide services to their customers with a lower cost, higher performance, better availability and scalability. However, privacy and security in cloud computing has always been a major challenge to service providers and a concern to its users. Trusted computing has led its way in securing the cloud computing and virtualized...
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)...
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...
