An efficient point‐to‐point security solution for multihop routing in wireless sensor networks

Abstract

Multihop enhances the performance of wireless sensor network (WSN); however, it is prone to several security and privacy issues due to its over‐reliance on intermediary nodes during transmission. Providing an effective security solution in WSNs with low computational cost is a challenging issue. Although there are several existing schemes to secure WSN, these schemes suffer from high computational cost in their authentication and signature verification processes, which reduces the overall performance of the network. In our scheme, we proposed an efficient lightweight security solution to mitigate security issues related to multihop routing in WSNs. A point‐to‐point authentication technique, additive perturbation, and symmetric encryption, using a novel key distribution and perturbs generation techniques to ensure data integrity and confidentiality during multihop routing, are engaged in our solution. As a result, our scheme is able to secure WSNs against possible known attacks and performs better than existing state‐of‐the‐art security scheme for multihop routing. The performance analysis shows that the proposed scheme requires low computational cost and secured against attacks.
