Abstract
Mobile Ad Hoc Networks are vulnerable to various types of Denial of Service (DoS) attacks for the absence of fixed network infrastructure. The Gray Hole attack is a type of DoS attacks. In this attack, an adversary silently drops some or all of the data packets sent to it for further forwarding even when no congestion occurs. In this paper, a new solution against the Gray Hole attack is proposed. The proposal is consisted of two related algorithms: the key management algorithm based on gossip protocol and the detection algorithm based on aggregate signatures. The simulation results using ns-2 show that in a moderately changing network, most of the malicious nodes could be detected, the routing packet overhead was low, and the packet delivery rate has been improved.
