Research of Secure Anycast Group Management

Because group management protocol and routing protocol of anycast are not so mature, when communicating it is easy to be attacked by malicious programs such as masquerading and denial of service, etc. Aiming at security of anycast, we propose a new secure anycast group management architecture based on others´ research in this paper. We setup a Certificate Authentication Server in the group management; it provides authentication service for any anycast server and anycast member to be joining in its group using PKI technology and secure communication mode. This architecture uses the advantages of related secure technology of multicast for reference and overcomes existing shortcoming of anycast group management protocols. This architecture has been proved to be feasible and effective through large numbers of simulation and experiments.
