Analysis of ECC for application specific WSN security

The range of applications based on Wireless Sensor Network (WSN) is wide and numerous. Security solution implementation is a major issue as these networks are formed from resource constrained tiny sensor nodes which have meager computational power and network lifetime. Moreover, the applications require different levels of security. A standard security solution is not feasible in such networks. Elliptic Curve Cryptography (ECC) is emerging as a promising security solution for WSN. Certain applications that require basic security level need not be burdened by using standard security measures which may tax on their efficiency. The right choice of values of parameters of Elliptic Curves (EC) is of paramount importance while implementing ECC for resource constrained WSN. This paper identifies the relevant parameters of EC for ECC implementation in WSN and analyses the impact of their values on the level of security they offer.
