Ad-hoc network is an autonomous mobile node. It is a set of temporary based networks, which has not fixed infrastructure. The Ad-hoc networks are very much positive towards attack by malicious node due to its vulnerabilities nature of routing protocols. There are large numbers of attacks affect the Ad-hoc networks. In between these attacks one is very much known as Black Hole Attack. The main propose of this paper is to prevent the intruders which carry the black hole node by key authentication manner and prevents it for doing any misbehave in network.
