The ‘‘smart grid (SG)’’ is an energy-based communication system, providing power generation, distribution, and consumption services for customers.[1]
To enhance the efficiency and reliability of SGs, the concept of dynamic microgrid partition has been proposed recently,[2] where all ‘‘smart meters (SMs)’’ in a SG are dynamically divided into multiple ‘‘microgrid groups (MGs).’’ Typically, the microgrid partition process is conducted by an entity called ‘‘Meter data management system (MDMS),’’ which determines the MG each SM belongs to

Summary

Introduction

The ‘‘smart grid (SG)’’ is an energy-based communication system, providing power generation, distribution, and consumption services for customers.[1]. It should be guaranteed that the group information management and message authentication processes are simple, when there are a lot of SMs and MGs. The scalability feature can be evaluated using three vectors (i.e. deployment complexity, computation cost, and communication cost). Designing a message authentication protocol for dynamic microgrid partition is a nontrivial task, because there are a variety of SMs as well as MGs, resulting in a lot of integrity and scalability issues. We present a novel message authentication protocol for SG called securing dynamic microgrid partition (SDMGP), which can fulfill all the above requirements. Using Lagrange interpolation and bilinear map, we design novel signing and verification algorithms to prevent adversary from tampering messages, which enjoys low computation and communication costs We analyze both the security and efficiency of SDMGP, showing it is feasible for real-world applications.
