PKHSN: A bilinear pairing based key management scheme for heterogeneous sensor networks

Abstract

Some applications of Wireless sensor network such as military and health-care applications require high level of security. Such a level of security cannot be provided through traditional key management schemes due to resource-constrained sensor nodes. Keeping this in mind, we propose a novel key management scheme with the following design objectives: (i) reduction of computation overhead (ii) reduction of communication overhead (iii) mitigation of node capture attack and (iv) protection from clone attack and replay attack. Here, we apply Identity-based cryptography which uses bilinear pairing on elliptic curves. The security of the proposed scheme is proved through Strand Space model. The analysis and experimental results infer that the proposed scheme provides better performance as compared to other similar protocols in the literature.
