Unlike the conventional routing techniques in the Internet where routing privileges are given to trustworthy and fully authenticated nodes, Delay Tolerant Networks (DTNs) allow any node to participate in routing due to the lack of consistent infrastructure and central administration. This creates new security challenges as even authorized nodes in DTNs could inject several malicious threats against...
The concept of byzantine attack comes from byzantine generals problem. In this abstract concept, the loyal byzantine army general are suppose to coordinate in a battlefield to conclude a common plan in the presence of traitor generals which can disrupt such coordination. This generals problem resembles the attacks initiated by authenticated nodes/devices in ad hoc network to disrupt the network. Although...
To secure a mobile ad hoc network (MANET) in adversarial environments, a particularly challenging problem is how to feasibly detect and defend possible attacks on routing protocols, particularly internal attacks, such as a Byzantine attack. In this paper, we propose a novel algorithm that detects internal attacks by using both message and route redundancy during route discovery. The route-discovery...
