Design of a Key Establishment Protocol for Smart Home Energy Management System

With the fast development of Wireless Sensor Networks (WSNs) and RFID technology, many Internet of Things (IOT) applications have been deployed in recent years. Smart home energy management systems form part of the smart grid program and are a fast developing smart home application area. Inadequate security is a big issue in smart home energy management systems. Most security protocols widely used for computer network and internet security cannot be implemented in smart home energy management systems as they are computational expensive for the wireless sensor nodes used in smart home applications. The major issue in the security of smart home energy management systems is the establishment of the initial session key between the wireless nodes and control center. In this paper, we propose a lightweight key establishment protocol for smart home energy management systems and present the implementation details of the protocol.
