Encryption and Authentication in Smart Grid Communication Security

Ensuring Secure Communication and Data Integrity in Smart Grid Technology

Abstract

Smart Grid technology can increase the efficiency of energy management. Conventional power grid systems are being replaced with new advanced Smart Grid systems. These Smart Grid systems rely on current Information and Communication Technology (ICT) to provide advanced services to both users and service providers. Due to increased use of ICT especially wireless communication makes Smart Grid system more vulnerable to physical layer attack such as Eavesdropping, Jamming, Restricting Access, Injecting and internal attacks. In this paper we are proposed encryption techniques for device authentication to protect from physical attacks. Device authentication is first step of data communication. We propose an efficient encryption key management for end to end security between two grids and algorithm steps secures the communication between the grids and maintains integrity of data.
