    Secure and User Efficient EAP-based Authentication Protocol for IEEE 802.11 Wireless LANs
    Wireless Local Area Networks (WLANs) have experienced significant growth in the last two decades due to the extensive use of wireless devices. Security (especially authentication) is a staple concern as the wireless medium is accessible to everybody. Extensible Authentication Protocol (EAP) is the widely used authentication framework in WLANs to secure communication. The authentication mechanism designed on EAP is called EAP method. There are numerous EAP based and non-EAP based authentication protocols for WLANs, but there is no protocol that fulfills all the security requirements, as mentioned in RFC-4017 and other additional requirements like perfect forward secrecy, Denial-of-service (DoS) attack protection, and lightweight computation. Hence, it is fair to infer that there is an impelling need to design a protocol that can meet all the security requirements. In this paper, we propose a secure and user efficient EAP-based authentication protocol for IEEE 802.11 WLANs. The proposed protocol has been formally validated by BAN logic and the AVISPA tool [18]. The simulation results depict that the proposed protocol achieves all security requirements, as mentioned in RFC-4017 along with perfect forward secrecy, Denial-of-service (DoS) attack protection, and lightweight computation. The proposed protocol outperforms the existing protocols in terms of computation cost by reducing the computation cost by ≈99.9956%, 99.991%, 27.27%, 22.705% in comparison to EAP-TLS, EAP-TTLS, EAP-Ehash, EAP-SELUA, respectively.

    An EAP-Based Mutual Authentication Protocol for WLAN connected IoT devices
    Several symmetric and asymmetric encryption based authentication protocols have been developed for the Wireless Local Area Networks (WLANs). However, recent findings reveal that these protocols are either vulnerable to numerous attacks or computationally expensive. Considering the demerits of these protocols and the necessity to provide enhanced security, a lightweight Extensible Authentication Protocol (EAP)-based authentication protocol for WLAN-connected IoT devices is presented. We conduct an informal and formal security analysis to ensure robustness against the attacks. Furthermore, the empirical performance analysis and comparison show that the proposed protocol outperforms its counterparts, reducing computational, communication, storage costs, and energy consumption by up to 99%, 80%, 91.8%, and 98%, respectively. Simulation results of the protocol using the NS3 and its overhead under unknown attacks demonstrate that the proposed protocol performs better in all scenarios. A prototype implementation of the protocol has also been tested to evaluate its feasibility in real-time applications.
