Abstract

Key management in wireless sensor network is a challenging task because public key cryptosystem are unsuitable for using in resource constrained sensor nodes, and the nodes could be physically compromised by a rival. Due to resource constraints, it is infeasible to apply traditional key management techniques in WSN. Numerous dynamic key management schemes have been proposed so far, for maintaining secure channels among communicating nodes but they all are not efficient in terms of resource constraints parameters. This paper proposes a dynamic key management scheme by combining the advantages of simple cryptography and random key pre-distribution scheme. In this, when distance between two nodes increases the remaining energy of nodes are also increases. This scheme enables to establish a secure links between any two communicated nodes. Beside this, it also removes node addition attack and increases the security strength within the cluster by introducing the cluster key. Finally, the security analysis show that proposed scheme is more efficient and meets the security needs of sensor network.

Abstract

Wireless Sensor Networks(WSNs) consists of low power, low-cost smart devices which have limited computing resources. With a widespread growth of the applications of WSN, the security mechanisms are also be a rising big issue. A lot of real-world applications have been already deployed and many of them will be based on wireless sensor networks. These applications include geographical monitoring, medical care, manufacturing, transportation, military operations, environmental monitoring, industrial machine monitoring, and surveillance systems. This paper discusses typical constraints, security goals, threat models and typical attacks on sensor networks and their defensive techniques or countermeasures relevant to the sensor networks, including security methods. The most critical area prone to attack is nearby the base station as the data is more aggregated, that should be kept secure using a number of defensive techniques as stated.
