Nodes in a wireless sensor network (WSN) are susceptible to various attacks primarily due to their nature of deployment and unguarded communication. Therefore, providing security in such networks is of utmost importance. The main challenge to achieve this is to make the security solution light weight so that it is feasible to implement in such resource constrained nodes in WSN. So far, data authentication has drawn more attention than the node authentication in WSN. A robust security solution for such networks must also facilitate node authentication. In this paper, a low overhead encryption based security solution is proposed for node authentication. The proposed node authentication scheme at the sender side consists of three modules viz. dynamic key generation, encryption and embedding of key hint. Performance of the scheme is primarily analyzed by using two suitably chosen parameters such as cracking probability and cracking time. This evaluation guides us in fixing the size of the unique id of a node so that the scheme incurs lowoverhead as well as achieves acceptable robustness. The performance is also compared with a couple of recent works in terms of computation and communication overheads and that confirms our scheme's supremacy over competing schemes in terms of both the metrics.

LMAC: A Lightweight Message Authentication Code for Wireless Sensor Network

Message authentication codes (MACs) are classically used for preventing unauthorized and corrupted messages from being forwarded in a network. However, inherent energy limitations of wireless sensor networks (WSNs) make the application of most of the state-of-the art MACs unaffordable due to their large computation overhead. Therefore in this paper, in order to cope with this challenging concern, we have proposed a lightweight hash based symmetric key message authentication code. The primary focus is on making the algorithm lightweight so that on using it in achieving secured communication in energy starved networks like WSNs, the resource constrained nodes can successfully run the algorithm. Detailed security analysis shows that LMAC also thwarts passive attack as well as active attack. Finally the comparative usability of the MAC in the said application domain is worked out and that shows the dominance of LMAC over several state-of-the-art MACs. We claim that on an average LMAC requires 61% less overhead compared to its competitors.

Wireless sensor networks (WSNs) are susceptible to various attacks, and these attacks pose a major threat to the normal functioning of WSNs. Jamming is one such attack, which affects network operations by blocking frequencies. Hence, the need of defending such attack is of utmost importance. This paper proposes three variants of a data forwarding scheme using multi‐level multi‐tier architecture, which employs judicious surfing of a pair of channels to defend jamming attack in WSNs. Variant I defends the attack at the cost of an affordable delay. Improvement of the scheme in minimizing data transmission time is made in variant II. Further improvement in transmission time is made in variant III and is made more realistic by introducing sensing capability at all tiers, thereby increasing network coverage. Simulation is performed to establish each of the successor's variant's improvement over its predecessor. The performance of the scheme in terms of area coverage, packet delivery ratio, and control message overhead is compared with an existing jamming‐defending scheme for infrastructure‐based wireless network. Finally, comparison results establish that although the proposed scheme is equivalent to its infrastructure‐based counterpart in terms of coverage, it provides a more lightweight solution and maintains improved performance in terms of packet delivery ratio.
