Abstract

A smart gird improves reliability and efficiency of the power network by actively engaging with customers. Increasing demand for energy, availability of untapped renewable energy, and an aging electric grid infrastructure have motivated researchers to redesign the current electric network . Advanced metering infrastructure (AMI) facilitates implementation of dynamic pricing and predicting load demand in an area through a communication system that also enables customer participation. The home area network (HAN), part of the AMI, is comprised of a smart meter and electric appliances used in the home. A wireless mode of communication is used in the proposed HAN to support the AMI. The exchange of data in a wireless medium is prone to various malicious attacks and interference issues since it is a shared medium. This work investigates security issues in the HAN since it constitutes a major building block for the smart grid. This paper discusses wireless security threats in HAN and possible security solutions. An experimental prototype of a secure wireless HAN framework is designed and implemented.
