WSN is an embedded system with the network properties of self configuration, self healing, dynamic routing and multi hop communication and sensor nodes are scattered in sensor field. WSN is ubiquitous in nature but nodes have limited energy resources and memory constraints, the protocols designed for sensor networks should be energy efficient. Security access to the sensor networks is a critical part of the network administration; due to wide availability of services and high mobility of users the strongest authentication methods are needed and hence the authors propose four factor user authentication protocols for a secured network. This scheme is based on multi factor such as password, smart card and a user finger print, phone factor.
