A Secure Way of Communication for Smart Grid Networks

open access: yesInternational Journal of Distributed Sensor Networks, Volume 2025, Issue 1, 2025.
In 2021, Khan et al. suggested a scheme based on smart grid networks. They deployed the random oracle model to justify the security of their scheme formally. They also verified the security of the scheme using the AVISPA software tool. We studied this scheme and found some security issues. The scheme suffers from a confidentiality breach attack.
