Trusted Detect And Measure For Virtual Machine System

Virtualization technology is a fast growing area for not only research but alsoapplication area in recent years. The virtualization technology includes software vir-tualization technology and hardware virtualization technology and it can bring conve-nience to the management of computing resources. And also, the virtualization tech-nology is a very important component of"cloud computing"technology. Togetherwith the development of the network and the"cloud computing"technology, the vir-tualization technology must be used more often in people's daily life. The securityproblem an important problem in nowadays computer system, especially in the net-work environment. To measure and verify the softwares and the computer system isan important method. Trusted computing technology is a technology which use thehardware method and software method to help protecting the computer system frommalicious attack.By combing the virtualization technology and the trusted computing technology,we can give out new methods to solve the traditional problems. The new methodsupport active measuring and verifying. And at the same time, the new method canprotected itself from the attacking by the malicious softwares.The goal of our work is to learn the measuring and verifying in the virtualizedcomputer system, to implement the protection of the system. We introduce an ac-tive trusted model, which includes subject, object, measure relation, trust relation, thetrusted system states and the transition between the trusted system states. Using thismodel, we can help to develop the measuring and verifying softwares in the virtualizedcomputer. And this paper will also introduce a active scan framework between virtualmachines.
