A Historical Role-Based Fast Negotiation Model in Open Network

In the open network, the resource requesters and providers often belong to different security domains. It can be achieved through automated trust negotiation(ATN) to build confidence among strangers and to ensure the security of shared resources. How to speed up the subsequent negotiation between these entities is the important issue. This paper analyzed the automatic trust negotiation and proposed the historical role-based fast negotiation model HRFN. HRFN introduces the concept of role. HRFN maps the counterparty to many roles connecting with many access privileges according to the credentials he disclosed during previous successful negotiation. HRFN records these roles with its credential disclosure sequence in the HIB. In the subsequent negotiation,the resource provider checks that if the requester has a role that is permitted to access the resources. If such a role exists,the negotiators can disclose credentials according to the credential disclosure sequence and then conduct a successful negotiation. After experimental verification, HRFN model was verified to has higher safety performance and also meet the rapid demand for automated trust negotiation.
