Secure and Efficient Privacy‐preserving Scheme in Connected Smart Grid Networks

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 …
