A design on Light-Weight Key Exchange and Mutual Authentication Routing Protocol in Sensor Network Environments

Abstract Wireless Sensor Networks is the technology which is used in explore role for military purposes, as wellas various fields such as industrial equipment management, process management, and leverage available technologies by distributing node into various areas. but there are some limitations about energy, processing power, and memorystorage capacity in wireless sensor networks environment, because of tiny hardware, so various routing protocols are proposed to overcome it. however existing routing protocols are very vulnerable in the intercommunication, because they focus on energy efficiency, and they can't use existing encryption for it, Because of sensor's limitations suchlike processing power and memory. Therefore, this paper propose mutual authentication scheme that prevent various security threats by using mutual authentication techniques and, Key generation and updating system as taking into account energy efficiency Keywords : LEACH, Sensor, Sensor Authentication, Sensor Network, Sensor Routing Protocol
