Abstract :Low computational power of wireless sensors and the multicast form of transmission exhibited by WBAN make it susceptible to several security and privacy issues. Due to these, many security and privacy preservation approaches had been proposed to secure and preserve privacy of nodes in WBAN. However, the inherent low computational power which characterises WBAN nodes made most of these approaches inefficient for the networks. This paper proposes a lightweight two-way but coordinated perturbation scheme for obfuscating both the identities and measurements of the sensor nodes in the network. This coordination eliminates security and privacy problems associated with perturbs exchange during reconstruction. The proposed scheme was evaluated by simulating the scheme and using output of digital ECG samples as a WBAN nodeâ€™s measurements. The simulation results show that the perturbation perform under a considerable time t = 0.67s efficiently obfuscated the node measurements.
