Trustworthy monitoring system for secret data transmission based on USB interface
Huang Hong-wen · Journal of Guangxi University · 2011
A data transmission monitoring system based on trusted mechanism is proposed in this paper,which is targeting at the problems in traditional monitoring system based on USB interface,such as the lack of medium identity authentication methods,the difficulty for conducting effective isolation of each grades,and the low credibility.In the proposed system,a two-way identity authentication scheme of combining dynamic password with fingerprint identification and a file filtering drive technology are applied,and a trusted chain model is built within the system in which trustworthy components are as trusted root,and a kind of multi-level security policy which combined security policies of driver layer with application layer is implemented to enhance access control of confidential information.By analyzing and testing the system,the results showed that the system was feasible and met to the confirmed trustworthiness level.
