The Design of Information Flow Control in the Trust Domain Based on the Trusted Terminal

The flow of information security is commonly controlled by different trust domains in the distributed environment. The information sharing in a unique trust domain, however, is also an essential issue to be further studied. Fortunately, the trusted computing technology provides a nice solution to elaborate the security of information sharing in the same trust domain. In this paper, trusted terminal is established through trusted computing technology, and the sharing information in trust domain is bounded with corresponding equipment group to achieve the division of trusted sub-domain, and the information is shared securely in a same trusted sub-domain, which can prevent malicious user´s illegal operation in the same trust domain.
