“…As in other hierarchical models of sensor network (Cheng & Agrawal, 2007;, our system also assumes that a sensor network is divided into clusters, which are the www.intechopen.com minimum unit for detecting events. A cluster head coordinates all the actions inside a cluster and each pair of cluster heads in their transmission range can communicate directly with each other.…”

“…WSNs can be broadly classified into flat WSNs and hierarchical WSNs. It has been shown in (Cheng & Agrawal, 2007) that a hierarchical architecture can provide better performance, in terms of communication overhead, than a flat architecture in such networks. This is the marjor reason why most recent lightweight energy efficient rekeying mechanisms are proposed for hierarchical WSNs.…”

Abstract-Research in Wireless Sensor Networks (WSNs) has made a significant progress recently, especially the area of key management, which plays a central role for protecting group communication in sensor networks. In sensor networks, the data are crucial and have to keep secrecy in data communication. To achieve data confidentiality, adversary should not have access to the group communication. Therefore due to the limited memory resources and energy constraints of sensor nodes, reducing the communication and storage overhead, and improving the resilience against the node capture attack become a must.In this paper we propose An Efficient Group Key Management using Symmetric Key and Threshold Cryptography for Cluster based Wireless Sensor Networks (EGKMST). The proposed scheme considers a hierarchical cluster structure of sensor network and adopts the pair-wise key management and group key management based on threshold key cryptography to generate and to distribute the keys efficiently within a cluster and updates periodically keys. By this way EGKMST provides continuous transmission security and avoids dangerous attacks from malicious nodes and mitigate the node compromise attack in WSNs communication. The security and performance analysis illustrate that EGKMST scheme achieves the requirement of group communication and provides efficient security with low communication cost, low memory overhead and energy saving compared with some existing key management schemes.

“…Under this arrangement, each sensor node forwards the generated packets to its local CH by short-range transmissions, and the CH then performs a pre-processing for the raw data received from all other senor nodes in the cluster and finally forwards the aggregated data to the sink node, or Base Station (BS), by long-range transmissions. It has been shown in [5] that a hierarchical architecture can provide better performance, in terms of communication overhead, than a flat architecture in such networks.…”

SUMMARYMany applications of wireless sensor networks (WSNs) require secure group communications. The WSNs are normally operated in unattended, harsh, or hostile environment. The adversaries may easily compromise some sensor nodes and abuse their shared keys to inject false sensing reports or modify the reports sent by other nodes. Once a malicious node is detected, the group key should be renewed immediately for the network security. Some strategies have been proposed to develop the group rekeying protocol, but most of existing schemes are not suitable for sensor networks due to their high overhead and poor scalability. In this paper, we propose a new group rekeying protocol for hierarchical WSNs with renewable network devices. Compared with existing schemes, our rekeying method possesses the following features that are particularly beneficial to the resource-constrained large-scale WSNs: (1) robustness to the node capture attack, (2) reactive rekeying capability to malicious nodes, and (3) low communication and storage overhead. key words: key management, group rekeying, hierarchical wireless sensor network, security
