An Empirical Study of Elliptical Curve for Wireless Sensor Networks

Development in Micro Electro Mechanical Systems (MEMS), Very Large Scale Integration (VLSI) and Wireless Communication has opened a new domain in networking area called Wireless Sensor Networks (WSN). WSN is a special case of a Mobile Ad Hoc Networks (MANET) in which information is gathered, processed and communicated with the help of tiny wireless sensor nodes that are deployed in the field where ordinary networks are unreachable for various environmental and strategic reasons. Wireless sensor nodes use radio frequencies as a communications medium, and are vulnerable to active and passive attacks from adversaries including node capturing, frequency jamming, and various Denial of Service (DOS) attacks. Most of the ongoing research is to make WSN secure with Symmetric Key (SK) protocols but at the same time Public Key Cryptography (PKC) has received little attention from researchers.This book explores use of elliptical curve cryptography for securing wireless sensor networks which is the potential candidate for wireless security in near future.
