Recently the security in vehicular ad hoc networks (VANETs) draws attention because of increasing vehicular applications. One of the main challenges of secured communication in VANET is multicast source authentication which essentially guarantees that the received data in communication is genuinely sent from the source and not modified by impersonators. Although much research has been focused on message...
Mobile ad hoc networks (MANETs) have many well-known applications in military settings as well as in emergency and rescue operations. However, a lack of infrastructure and centralized control make MANETs inherently insecure, and therefore specialized security services are needed for their deployment. Self-certification is an essential and fundamental security service in MANETs. It is needed to securely...
Key management is important to security of mobile ad hoc network (MANET). Based on the (t, n) threshold cryptography, this paper introduced mobile agent to exchange private key and network topological information with nodes in the network. This method cannot only reduce the network overload, but also improve the service velocity and success ratio of authentication. Any t nodes in the network sized...
Adhoc networks are self-configurable networks with dynamic topologies. All involved nodes in the network are responsible for management activities. In multihop adhoc environment, it is difficult to maintain paths through intermediate nodes, due to the mobility of nodes, nature of radio transmission etc. In the absence of an authentication mechanism, malicious nodes can easily corrupt route tables,...
