Classification of EAP methods and Some Major Attacks on EAP

This paper presents an overview of authentication protocol and analysis of Extensible Authentication Protocol (EAP) and its place in securing network. In general, authentication procedure adds extra messages to the original message flow and results in throughput reduction/ increase in processing time. Extensible Authentication Protocol (EAP) is a framework which aims to provide a flexible authentication for wireless networks. A number of specific widely used EAP methods are examined and evaluated for their advantages and susceptibility to types of attack. In addition, we evaluate how we communicate between two entities over the network

Selection of EAP-authentication methods in WLANs

IEEE 802.1X is a key part of IEEE802.11i. By employing Extensible Authentication Protocol (EAP) it supports a variety of upper layer authentication methods each with different benefits and drawbacks. Any one of these authentication methods can be the ideal choice for a specific networking environment. The fact that IEEE 802.11i leaves the selection of the most suitable authentication method to system implementers makes the authentication framework more flexible, but on the other hand leads to the question of how to select the authentication method that suits an organisation’s requirements and specific networking environment. This paper gives an overview of EAP authentication methods and provides a table comparing their properties. It then identifies the crucial factors to be considered when employing EAP authentication methods in WLAN environments. The paper presents algorithms that guide the selection of an EAP-authentication method for a WLAN and demonstrates their application through three examples

A Review of Authentication Protocols

Authentication is a process that ensures and confirms a users identity. Authorization is the process of giving someone permissions to do or have something. There are different types of authentication methods such as local password authentication, server-based-password authentication, certificate-based authentication, two-factor authentication etc. Authentication protocol developed for Password Authentication Protocol (PAP), Challenge-Handshake Authentication Protocol (CHAP), and Extensible Authentication Protocol (EAP). There are different types of application for authentications are as follows: 1.protocols developed for PPP Point-to-Point Protocol 2. Authentication, Authorization and Accounting 3.Kerberos

Formalization and evaluation of EAP-AKA’ protocol for 5G network access security

The end user’s Quality of Experience (QoE) will be improved while accessing services in Fifth Generation Mobile Network (5G), supported by enhanced security and privacy. The security guarantees offered by the Authentication and Key Agreement (AKA) protocols will be depended upon by end users and network operators. The AKA protocols have been standardized for 5G networks, and the Extensible Authentication Protocol (EAP)-AKA’ protocol is one of the main authentication mechanisms that has been specified for User Equipment (UE) and network mutual authentication. This article models the EAP-AKA’ protocol and conducts an extensive formal verification of the EAP-AKA’ protocol as defined in the 5G security standard to determine whether the protocol is verifiably secure for 5G. It provides a security evaluation of the EAP–AKA’ protocol based on the current 5G specifications using ProVerif, a security protocol proof verifier. It also presents security properties that support the security verification, as well as quantitative properties that are used to assess the protocol’s performance. Finally, it compares the EAP-AKA’ and 5G-AKA protocols’ security and performance results

Extensible Authentication Protocol Vulnerabilities and Improvements

Extensible Authentication Protocol(EAP) is a widely used security protocol for Wireless networks around the world. The project examines different security issues with the EAP based protocols, the family of security protocols for Wireless LAN. The project discovers an attack on the subscriber identity module(SIM) based extension of EAP. The attack is a Denial-of-Service attack that exploits the error handling mechanism in EAP protocols. The project further proposes countermeasures for detection and a defense against the discovered attack. The discovered attack can be prevented by changing the protocol to delay the processing of protocol error messages

Simple authentication and security layer incorporating extensible authentication protocol

There are many methods that support user authentication and access control, important roles in the establishment of secure communication. Particularly, we examine Simple Authentication and Security Layer (SASL) and Extensible Authentication Protocol (EAP) and propose EAP-Advanced Encryption Standard-Pre-Shared-Key (EAP-AES-PSK). SASL is an authentication framework in connection-oriented protocols. EAP is an authentication framework providing multiple authentication methods. SASL is vulnerable to the dictionary attack, replay attack, and Man-In-The-Middle attack as well as the re-keying issue. We propose to incorporate EAP into SASL to enhance the security of SASL and to provide a pathway for easy incorporation of future EAP enhancements into SASL. Standalone EAP still faces some common attacks. We propose EAP-AES-PSK, a new EAP method, to provide strong authentication and we implement this method on the Cyrus SASL implementation: one of the publicly available SASL implementations. This project is evaluated through the verification of functionality of a SASL application incorporating EAR Further, we argue how the common security risks associated with SASL are addressed, and we complete a performance evaluation of the new method incorporated into SASL

Enhancements to Secure Bootstrapping of Smart Appliances

In recent times, there has been a proliferation of smart IoT devices that make our everyday life more convenient, both at home and at work environment. Most of these smart devices are connected to cloud-based online services, and they typically reuse the existing Wi-Fi network infrastructure for Internet connectivity. Hence, it is of paramount importance to ensure that these devices establish a robust security association with the Wi-Fi networks and cloud-based servers. The initial process by which a device establishes a robust security association with the network and servers is known as secure bootstrapping. The bootstrapping process results in the derivation of security keys and other connection parameters required by the security associations. Since the smart IoT devices often possess minimal user-interface, there is a need for bootstrapping methods with which the users can effortlessly connect their smart IoT devices to the networks and services. Nimble out-of-band authentication for Extensible Authentication Protocol (EAP-NOOB) is one such secure bootstrapping method. It is a new EAP authentication method for IEEE 802.1X/EAP authentication framework. The protocol does not assume or require any pre-configured authentication credentials such as symmetric keys or certificates. In lieu, the authentication credentials along with the user’s ownership of the device are established during the bootstrapping process. The primary goal of this thesis is to study and implement the draft specification of the EAP-NOOB protocol in order to evaluate the working of EAP-NOOB in real-world scenarios. During our implementation and testing of the initial prototype for EAP-NOOB, we discovered several issues in the protocol. In this thesis, we propose a suitable solution for each of the problems identified and also, verify the solutions through implementation and testing. The main results of this thesis work are various enhancements and clarifications to the EAP-NOOB protocol specification. The results consequently aid the standardisation of the protocol at IETF. We also design and implement several additional features for EAP-NOOB to enhance the user experience

Compact extensible authentication protocol for the internet of things : enabling scalable and efficient security commissioning

Internet of Things security is one of the most challenging parts of the domain. Combining strong cryptography and lifelong security with highly constrained devices under conditions of limited energy consumption and no maintenance time is extremely difficult task. This paper presents an approach that combines authentication and bootstrapping protocol (TEPANOM) with Extensible Authentication Protocol (EAP) framework optimized for the IEEE 802.15.4 networks. The solution achieves significant reduction of network resource usage. Additionally, by application of EAP header compacting approach, further network usage savings have been reached. The EAP-TEPANOM solution has achieved substantial reduction of 42% in the number of transferred packets and 35% reduction of the transferred data. By application of EAP header compaction, it has been possible to achieve up to 80% smaller EAP header. That comprises further reduction of transferred data for 3.84% for the EAP-TEPANOM method and 10% for the EAP-TLS-ECDSA based methods. The results have placed the EAP-TEPANOM method as one of the most lightweight EAP methods from ones that have been tested throughout this research, making it feasible for large scale deployments scenarios of IoT
