Strong Security Scheme for Single Node and Colluding Nodes Byzantine Attacks in MANETS

Abstract

                  Mobile Ad Hoc networks are the wireless networks and are established spontaneously without any fixed infrastructure to connect the devices for communication and sharing resources. Almost all of these devices are connected using radio network and this radio network is vulnerable to attackers of all kinds from novice to specialists and all sorts of attacks from active to inactive attacks. Though MANETs have profound use in many fields, the major application areas are disaster recovery, military field, IoT, VANETs and also used in crucial and life saving areas of health care systems. One of the active attacks is Byzantine attack and it has various forms such as black hole, worm hole and distributed denial of service. These attacks can be executed by single node or by multiple colluded nodes to stamp the entire network. The system presented in this paper provides a mechanism for reliable and secured communication against all forms of Byzantine attack with strong authentication. The nodes actions are monitored in each and every layer and the feedback of the nodes is generated as weights in Kirchhoff’s matrix. This is passed to the contact layers used in network activities from route establishment to message transmission. This cross layer feedback along with other secured mechanisms defends against all forms of Byzantine attacks in all stages from detection and recovery to prevention.
