Abstract

In a connected smart grid, several kinds of sensors have been integrated in smart meters to measure energy usage and execute the control commands and/or instructions from the utility companies. This becomes possible through the digital processing and communications organized in the smart grid (SG) networks. As, a smart grid enables the two‐way communication between the electricity supplier and users, an efficient security solution should be integrated in the SG in order to guarantee the user's privacy and authenticity of the data. This chapter proposes a secure and efficient privacy preserving scheme based on elliptic curve cryptography, outperforming both in computation and communication the best currently available schemes in literature. The proposed scheme is resistant against internal attackers, provides authentication, integrity and confidentiality. In addition, it offers the possibility of pinpointing the smart meter that is providing false input. The security features of confidentiality and unforgeability are formally proven.

13.1 Introduction

The traditional power plants were concentrated systems where the energy flow was unidirectional bulk generation to domestic or industrial consumers via the traditional transmission and distribution lines. The new idea of connected smart grids is a paradigm for distributed power generation and consumption which requires ...
