The Study on Hardware Protection in Cloud Computing by Virtualization Technologies

Cloud computing make wave-tech-neologies virtualization, is becoming a computation model of the mainstream. Many companies started to use infrastructure-as-a-service cloud computing model (IaaS), leasing guest virtual machine (VMs) from infrastructure providers: because of economic reasons, in order to reduce operating costs, improve their infrastructure flexibility. However, many companies might hesitate to move to cloud computing, with security problems. An integral part of any virtualization technology is the almighty program. A program is a system management software layer can access all resources platform. People do a lot of research, using hypervisors observation of the guest malicious code and in this hypervisors sclerosis, make them more secure. However, another threat, it did not mention personnel-hypervisors compromise or malicious, and can extract sensitive or confidential data from the boat. Therefore, we put forward a new research direction needs to take respond to this threat. We further puts forward new hardware mechanism of multiple processors is a feasible method for the guests to provide protection of the program, and this is still allowed to flexible management program of physical resources platform.
