EMICKS: - Effective Method in Cluster based Key Management in Ad Hoc Networks
Ruth Ramya Kalangi, K. Pradeepa · 2014
Abstract — Mobile ad hoc networks are dynamically reconfigured networks in which security is a major concern. MANETS face serious security problems due to their unique characteristics such as mobility, dynamic topology and lack of central infrastructure support. Key management is crucial part of security. This issue is even bigger in MANETS. A challenge of the key distribution scheme is to use small memory size to establish secure communication among a large number of nodes. To provide good scalability in terms of the number of nodes and storage space, we utilize a combinatorial design of public-private key pairs. To reduce the overhead and for high service availability, we divide the network into clusters. Cluster head distribute the key pair. The performance results show that without clusters in a network, the metrics of overhead, time delay, key usage are more, whereas in our proposed scheme by the formation of clusters, it is greatly reduced due to its distributed behavior.
