Free registration required

Executive Summary

Wireless Sensor networks are a new wireless networking paradigm for the mobile hosts. Wireless Sensor networks are an autonomous system that is made up of collaborative mobile nodes. Wireless Sensor networks can be dynamically setup without relying on any pre-existing infrastructure. Implementing the public key user authentication is a challenging issue in Wireless Sensor networks due to its salient nature of the network. The user authentication is of three steps. In the first step Registration of user will be happened, in the second step user smart card will be validated with symmetric key and using the key the authentication of the user will be done as a third phase.
