ENSURING SMART GRID DATA SECURITY AT CLOUD DATA CENTRES

Abstract

In the world of evolving technologies the energy like solar or electricity and utilities industry, plays major role includes smart meters and smart grids, which provides companies with exceptional capabilities for forecasting demand, determining customer usage patterns, preventing outages, minimizing the loss and more. Advances in technologies and its usage generates unprecedented data volume, speed and complexity which should be preserved securely for later usage for accurate predictions. Managing the large volume information generated by short-interval reads of smart meter data by various smart devices is a challenge for existing IT resources in storing them and also ensuring the privacy of sensitive customer meter data is also a major issue in smart meter deployments. Security should be provided for data which is stored at data centers at cloud and also at local energy distributer centers at two tiers. In this paper we focus on security regarding storage of big data at data centres as well as at local distribution such as databases. So we propose MDET (Multiple Data Encryption Technique) which allows encryption of each record two times at storage centres by using Generator based encryption technique. In this technique the data in the database is encrypted twice so that the data record should be decrypted once at data centre as well as at the local distribution centre by private keys at two levels so that privacy of consumer data is not lost at either data storage centre at cloud or at local distribution centre.
