<p>A method and a broadband access device for improving the security of neighbor discovery in IPV6 environment are provided. The neighbor node solicitation messages sent by the user nodes are controlled and replied only by the broadband access device uniformly, without being forwarded to other user lines, and the other users can not launch an attack by neighbor discovery request, so that the communication of the node attacked by Denial of Service is interdicted effectively and the paralysis of the whole link communication is avoided. The implementation of the invention can provide IPv6 network with the secure neighbor discovery mechanism, and in the basic of ensuring the normal service data of the user node, ensure the IPv6 address information against being diffused to other user lines, so that the security of user data stream is guaranteed.</p> |
