Research On Role-based Dynamic Access Control In Hybrid P2P Network

P2P technology is currently more popular as a network model, hybrid P2P combines the technological advantages of both sever-based mode and P2P mode, making the whole system more stable and reliable.JXTA is a development platform for P2P application. Its main purpose is to provide communications and services between each other. However, the JXTA platform only provides membership authentication protocol, not support global access control policy for the whole system. is intended to enable the different P2P systems can easily communicate with each other, working together to provide services to each other. But the JXTA platform provides only membership authentication protocol, the lack of a system of global access control policy. Access control is essentially limited use of resources, and decide whether one peer is authorized to implement certian operations to another peer.In this paper, we propose a novel access control model based on existing access control technology and the advantages of JXTA. Our work is inspired by RBAC model. Our model introduces a series of strategy mechanism from releasing resource to accessing resource. First, we introduce module separation strategy based on hybird P2P model. Then we study the dynamic role classification strategy and the mechanism of auto-distribution for role level. In addition, we provide a aggrement policy between peer-groups based on JXTA platform. Finally, we describe the mechanism for granting certificate and discovering certificate chain, and construct a dynamic, integrate and secure access control model for JXTA platform...
