Abstract

Summary: The smart grid is a new and promising technology integrating new information and communication technologies to improve the distribution and consumption of electricity between energy suppliers and their end customers. However, this advanced solution is facing a serious security problem as regards the interception and falsification of power consumption data, hence generating falsified electricity consumption bills. This issue of security needs to be promptly and efficiently handled. Clearly, it is of paramount importance to have a security mechanism to avoid such losses. Our work focuses on this issue. It particularly concerns the development of a security mechanism to ensure a completely secure communication between energy suppliers and their consumers while preserving the privacy of end customers in terms of protection of their personal information including their identities. The experimental results underscore that our solution outperforms those of the literature in terms of computation cost and robustness against various types of attacks. Abstract : In this manuscript, we have developed an anonymous authentication scheme that meets the privacy requirements of smart meters and perfectly ensures secure communication between energy suppliers and its smart meters against any type of attack aimed at their disclosure during their migrations into the smart grid. The main motivation for our solution is the use of lightweight cryptographic primitives, such as hash functions, concatenation, and multiplication operations. These primitives have shown that our security scheme has a better computation time compared to the schemes suggested in the literature and surpasses its competitors in terms of robustness against different types of attacks that can compromise the smart grid.
