A Framework for Secure Anycast Group Management

Anycast is a communication mode in which the same address is assigned to a group of servers and a request sent for a service is routed to the \´best" server. Because the group management and the routing protocol in the anycast are not so mature, there are distinct and significant security vulnerabilities in both the anycast model including denial of service, theft of service, eavesdropping, and masquerading. We propose a new framework for secure anycast group management, which overcome disadvantage of others anycast group management architecture, and can ensure the security of anycast server and the secure communication between anycast client and server. This method has been proved to be effective.
