Secure Routing in Wireless Sensor Networks using Identity-based Cryptography

Wireless Sensor Networks (WSN) have played a crucial role in many military and civilian applications. However, with the increase in popularity of such networks, the demand for security is also increasing proportionally. The new sophisticated attacks can easily compromise these resource constraint networks such as WSN. In this paper, we propose a location and energy efficient routing scheme using identity bases cryptography. We review the classical selective forwarding attack on WSN and see how an identity-based cryptographic scheme using a cross-layer design approach is helpful in circumventing such an attack. In addition, we show that an identity-based cryptographic approach to routing in WSN is more pragmatic then the traditional public key infrastructure (PKI) based schemes.
