Cantor Pairing lightweight key generation for wireless body area networks

Abstract

Wireless Body Area Networks (WBAN) are getting grandness due to the low-cost digital sensor communication devices. Implantable tiny sensor nodes and wearable sensor nodes are getting membership in a WBAN network. The characteristics of these member nodes are hugely different in terms of processing power and communication technology. Therefore, the nature of a WBAN network comes under heterogeneous category. Combining different types of nodes under one roof with a communication protocol is one of the perplexed tasks of WBAN. Security and Power consumption are the prime concerns in WBAN networks. High security communication protocols consume more power whereas low power consuming protocols lack some security. Equilibrating the balance between power, performance and security is an inevitable chore while designing communication protocols for WBAN. This work named as Cantor Pairing Light Weight Key Generation (CPLKG) is targeted to improve the security without impacting the performance in terms of Throughput, End-to-End delay, Packet Delivery Ratio, Memory and Power consumption. Device ID Hash Function (DHF), Cantor Pairing Key Generation (CPKG) and Cantor Pairing Key Revocation (CPKR) are the contributed functional blocks used to construct the proposed CPLKG method.
