Biometric mechanisms of authentication are becoming a popular approach to securing computer systems, networks and other critical resources. This paper proposes a behavioural authentication system based on user interaction with computer games. Literature about current physical and behavioural biometric methods is reviewed and game based authentication design and implementation issues are discuss...

This document specifies an Extensible Authentication Protocol (EAP) mechanism for authentication and session key distribution using the UMTS AKA authentication mechanism. AKA is based on symmetric keys, and runs typically in a UMTS Subscriber Identity Module, a smart card like device. AKA provides also backward compatibility to GSM authentication, making it possible to use EAP AKA for authentic...

The Extensible Authentication Protocol (EAP) describes a framework that allows the use of multiple authentication mechanisms. This document defines an authentication mechanism for EAP called EAP-EKE, based on the Encrypted Key Exchange (EKE) protocol. This method provides mutual authentication through the use of a short, easy to remember password. Compared with other common authentication metho...

Authentication is one of the essential security features in network communication. Authentication process ascertains the legitimacy of the communicating partners in communication. In authentication process, the originator of the communication and the respondent transacts some identification codes of each other prior to start of the message transaction. Several methods have been proposed regardi...

The protocol design for wireless roaming authentication is challenging because of the key management regarding users and home/visited networks. In this paper, we present two authentication methods that demonstrate better performance in terms of authentication latency and energy consumption of a mobile terminal, compared to the 3G cellular network approach of home network transporting authentica...

Usability and security challenges with standard text passwords have led researchers and professionals to consider alternative authentication schemes. This thesis explores the various challenges inherent in supporting a practical reality of authentication scheme diversity. We address these challenges by proposing the following solutions aimed at providing users with a usable and secure authentic...
