Abstract: A secure distributed solution is proposed in this paper according to the characteristics of anycast group management.Operations of group member such as joining and exiting are first authenticated by other members of the group.These members send relevant orders to every anycast router to complete the corresponding operations.By dividing members into smaller groups, monitoring between group members is performed.Cipher text is used when datagrams among members and the update message from members to anycast routers are transmitted.The analysis indicates that this scheme can satisfy the delay requirements of anycast group management, and is secure, robust and scalable.

Key words: PKI, group management, anycast, security
