A Central-Controllable and Secure Multicast System for Universal Identifier Network

In recent years, many institutes and organizations have been made efforts into developing new networkarchitecture. Universal Identifier Network(UIN) is one of them which is designed to providebetter mobility, better security and better reliability. Multicast is the basic network layer service thatis designed to save bandwidth for the whole network. The deployment of existing multicast schemeis restricted because of low security and the lack of control in sources. In this paper we have designeda central-controllable and secure multicast(CCSM) system for UIN that aims to achieve bettersecurity and scalability. We design the group management protocol and multicast routing protocol.The former one restricts the group members’ joining with authentication and the latter one provides asecure way to install multicast entries on routers. We evaluate CCSM by comparing it with PIM-SM,and the results show that CCSM is more secure and reduces the multicast flow entries for the wholenetwork.
