A secure way of communication for smart grid networksTyagi, Pooja (Avtor) Kumari, Saru (Avtor) Alenazi, Mohammed J. F. (Avtor) Hölbl, Marko (Avtor) key agreementsmart gridsmart grid networksuser authenticationIn 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. In Khan et al.’s scheme, an adversary can track both the user and the server, and it does not provide user and server anonymity. An adversary can also impersonate a server. To overcome all these security issues, we propose a protocol for smart grid networks. In our proposed scheme, we maintain all the qualities of Khan et al.’s scheme and try to remove all its weaknesses.Wiley20252025-12-01 13:43:09Članek v reviji96083sl© 2025 Pooja Tyagi et al.
