Trusted Terminal Design of Distributed Environment

In the distributed environment, one important security issue is how to apply further security control to the object that is released to other terminals. The appearance of trusted computing technology has provided an effective solution for this issue in the distributed environment. At the same time, through combining trusted computing technology with the strong isolation and sharing characteristic provided by virtual machine technology has further increased the security and the flexibility of distributed access control. Therefore, this paper uses trusted computing technology to improve the security of the terminal in carrying out the distributed access control, designs a trusted terminal architecture that bases on the trusted computing technology and the virtual machine technology as well as a enhanced mode that suits in distributed access control, and on this basis, analyzes the security of system design.
