Simple and secure node authentication in wireless sensor networks

Wireless sensor network (WSN) comprises of several nodes usually called motes or sensors. These motes gathered together and collect data by observing the surroundings and reported the information to one or more reliable links. This valuable data only be accessible between two communicating parties. To secure the data that delivers between the two parties, we require a secure node authentication scheme. Wireless sensor networks are special networks which attract several researchers due to the variety of applications but at the same time it suffers from many hazards. There are many guaranteed solutions but authentication assumes to give the best result among them. But sometimes it would be an energy consuming process. So, we need a safe and energy efficient mechanism to secure the whole network. In this paper, we have proposed a mechanism to authenticate nodes in a WSN. The proposed mechanism is simple and secure.
