The Design And Implemetation Of A Virtual Trusted Computing Platform Framework

The virtualization technology progress in a fast pace,it saves much of hardware resources for users.It enhances the usabilities for the companies who need a great number of servers and workstations to establish datacenter or website,and it costs less.However,we have to worry about the security situation of virtual machines,and using trusted computing in virtual machine is still at the begining.The goal of this design is to manage several DomainUs by using trusted computing technology and methodology,to support every DomainU with a virtual trusted device,to register virtual device when startup DomainU,to realize the trusted device communication between the DomainO and DomainU,to log their runing situations and put all the virtual enviroments into the trusted chain of safety computer architecture.Firstly,this paper transforms the TPM-Emulator from kernel module to deamon process architecture,makes the TPM-Emulator running out of system kernel.Secondly,this paper develope a virtual TPM for multi-DomainU and can be managed by virtual TPM device manager.Last but not least,the supporting for virtual TPM was attached to the virtual machine,this design developes a initial script and startup script for virtual TPM, it establishs a communication channel for virtual TPM and do system integrated measurement when launching virtual machine.This paper constructs a trusted chain completely,realize a virtual trusted computing platform framework finally.
