“…In [27], the authors proposed a protocol based on mobile agents to save energy and increase reliability while routing. In [24], the authors proposed an authentication protocol for wireless sensor networks based on dynamic keying approach. However, it is not applicable straight away into a MANET environment in which frequent topology changes occurred due to node join or leave or moving around.…”

Spontaneous group communication can be attained by deploying Mobile Ad Hoc Networks (or MANETs).The limitations thrown by these networks, motivate the necessity of a group key management framework to secure data traffic. In this context, significant research work done in the last decade and proved that the trust based frameworks deliver better performance than others. Trust value can be evaluated based on direct and indirect interactions with other nodes in the network. The threshold trust value does binary classification about a node is genuine or fake (misbehavior) and further communication includes or excludes. However, in many automated systems, the result for a given input cannot be just categorized as binary output. Instead of a binary, it is more spontaneous and natural to use a fuzzy set based classification which gives the degree of genuineness. To realize this concept, we propose a reliable group key management framework by adding fuzzy logic rules in this paper. The clustering scheme with Fuzzy classifier aids, to eliminate the pretended nodes over a span of time in order to evade internal attacks. Moreover, it saves the energy of each node due to lightweight framework and less key management overhead. Our simulation outcomes prove that our method is more reliable compared to existing frameworks.

Instant collaborative group communication can be achieved by deploying Mobile Ad Hoc Networks (or MANETs) without any pre-plan and pre-existing infrastructure setup. However, the curbs thrown by these networks, motivate the necessity of a group key management framework to secure data traffic. In this context, significant research work done in the last decade and proved that the trust based frameworks deliver better performance than others. In MANETs, trust quantified as the belief held by a node about another node. It is evaluated based on the assessing node direct experiences with assessed node itself, if they are neighbors and recommendations from remote nodes in the network with which assessed node has a direct experience, if they are remote. However, the framework based on recommendations by other nodes in the network might ultimately lead to system failure due to the menace of unfair recommendations by selfish and malicious nodes. Lying and on-off attacks on the system are such type of attacks. This motivates us to work on a framework which is immune to aforesaid attacks and should be lightweight due to node's has limited computing resources. We propose a framework which scrutinizes dishonest recommendations based on the trust threshold value of remote nodes, distance from mean of trust recommendations and by maintaining a history of recommendations. Our simulation outcomes prove that proposed framework can deliver better network performance and resistance to lying and on-off attacks.
