This research proposes network access control model based on the trusted label. The model combines the admission access control of network device and the transmission access control of data flow effective, and uses the trusted computing technology to ensure the credibility of the generated label, and adopts the access control based on the security domain to locate the granularity of access control to every packets, reduces the probability of successful attack to the network based on the information flow, thereby improving the security control of the network.
Trusted Network is a new research direction of the Internet. On the basis of trusted LAN, this study puts forward a trusted label of the trusted terminal, which can solve the DDOS attack efficiently and control the abnormal flow easily in the trusted LAN. In addition, it proposes the label’s verification technology, so as to ensure the execution efficiency of some real-time business in the gateway. Above all, the trusted label and the verification technology make the LAN more controllable and safer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
