Preventing bad prefixes attack in IPv6 stateless address auto-configuration protocol

Stateless address auto-configuration protocol in IPv6 is found to be vulnerable to bad prefixes attack wherein malicious node in the network can misconfigure hosts in the network so as to cause disruption in the communication between nodes in the same subnet or in different subnets. This paper proposes solution to prevent this type of attack. Initially this paper demonstrates existence of such vulnerability in Linux operating system. At the end of this paper implementation of prevention technique and results are presented.
