Lightweight Mutual Authentication Routing Protocols Design Based on LEACH in Sensor Network Environment
Wireless sensor network technology is a technology that distributes nodes into various areas which is useful in various fields such as exploration for military purposes, and device management, process management, and monitoring specific areas in industry. However, sensor node in wireless sensor network due to use of compact hardware has limitations in energy, processing power, and memory storage, and to overcome these limitations various routing protocols have been suggested. However in the case of existing routing protocol, it focuses on energy efficiency, it is very vulnerable to security in mutual communication, and there is limitations in implementing previous encryption system to overcome this, due to the lack of sensor processing power and memory. Therefore, this study suggests a mutual authentication method that can respond to various security threats by simultaneously introducing mutual authentication, key generation and updating system in the communication process that also considers energy efficiency.
