Recently, Zahednejad and Gao (2025 Journal of Information Security and Applications, Elsevier, https://doi.org/10.1016/j.jisa.2025.104083,) identified key compromise impersonation (KCI) in both, a two-factor, and a three-factor authentication protocols for IoT devices. They further proposed a lightweight authentication scheme designed to mitigate the identified KCI threats. Subsequently, Zhang et al. (2025, IEEE Transactions on Information Forensics and Security, https://doi.org/10.1109/TIFS.2025.3599678) introduced a chaotic map-based authentication protocol for the Internet of Drones, claiming that their design is resilient to a wide range of security attacks. Earlier, Kumari et al. (2019)... More >
