摘要

The integration of Internet of Things (IoT) devices into Wireless Local Area Networks (WLANs) creates significant security challenges, demanding robust authentication protocols that counter emerging cyber threats while ensuring dependable connectivity. While numerous symmetric and asymmetric encryption protocols exist, many remain vulnerable to various attacks. This paper introduces a novel EAP-based authentication protocol for WLAN-IoT environments that leverages Elliptic Curve Cryptography (ECC). Our protocol has been developed for mutual authentication and key agreement. A thorough security analysis, utilising both formal and informal techniques, illustrates the protocol’s robustness against recognised and emerging threats. The outcome of the test demonstrates that the suggested method is exceptionally appropriate for IoT applications, offering enhanced security with reduced computational and communication overhead relative to leading protocols. We validate our protocol through an exhaustive security analysis, incorporating formal verification via the Scyther tool and proofs within the Real-or-Random (ROR) paradigm, therefore illustrating robustness against all recognised threats. A comparative performance evaluation indicates that the suggested protocol decreases overall computational expenses by approximately 32% to 97% relative to the next most secure current method, while sustaining a lower communication overhead than the majority of asymmetric alternatives. These findings validate that our approach attains an exceptional security-performance equilibrium, rendering it a viable and resilient option for safeguarding WLAN-IoT implementations.
