Cryptographically secure privacy-preserving authenticated key agreement protocol for an IoT network: A step towards critical infrastructure protection

The idea of the Internet of Things (IoT) network has been created as a result of the coordination of different developments, constant handling, intellectual capacity, item sensors, and inserted frameworks. Recently, IoT devices have made big impact on industrial critical infrastructures. However, security and privacy of IoT critical infrastructure still, is the big concern. Therefore, to address the vulnerabilities of the existing frameworks, this paper proposes a cryptographically secure privacy-preserving authenticated key agreement scheme for a IoT network through an elliptical curve, which generates a mutual key between the user and the device. The safety review and systematic testing of the system using the Automated Validation of Internet Security Protocols and Applications (AVISPA) method have been carried out to show the protection quality of the system. The quality review reveals that the scheme is lightweight and effective. By comparison, the proposed scheme is found to be comparable to the related works, and the current framework offers additional features such as Key Compromise Impersonate Attack Resistance, Established Session Key Protection, Key Replication Resistance, in addition to existing features.
