Abstract: In wireless sensor network, the sensor nodes are connected to each other wirelessly and the nodes are able to enter and exit the network randomly without any prior intimation. This makes the entry of the malicious nodes into the network easy, thus making the network susceptible to various attacks. One of such attacks is jamming the transmission lines and hence corrupting the data being transmitted. In this paper, we propose to develop a dynamic key management system based on which the data message hops from one channel to another during data transmission. Since the data transmission occurs through a channel only for small duration, channels keeps changing. This minimises the probability for the attackers to determine the active channel and attack it; in order to corrupt the data.

Keywords: wireless sensor network; WSN; dynamic key management; channel hopping; jamming.
