This document specifies an Extensible Authentication Protocol (EAP) mechanism for authentication and session key distribution using the GSM Subscriber Identity Module (SIM). The mechanism specifies enhancements to GSM authentication and key agreement whereby multiple authentication triplets can be combined to create authentication responses and encryption keys of greater strength than the indiv...

Password authentication is the most commonly accepted means for entity authentication. To meet the increasing need of preserving individual privacy, anonymous password authentication has been proposed recently, to augment password authentication with the protection of user privacy. In this paper, we analyze the weaknesses inherent to anonymous password authentication, which make it questionable...

We propose new authentication protocols to support fast handover in IEEE 802.11-based wireless mesh networks. The authentication server does not need to be involved in the handover authentication process. Instead, mesh access points directly authenticate mobile clients using tickets, avoiding multi-hop wireless communications in order to minimize the authentication delay. Numerical analysis and...

The prevalence of computers and the development of the Internet made us able to easily access information. As people are concerned about user information security, the interest of the user authentication method is growing. The most common computer authentication method is the use of alphanumerical usernames and passwords. The password authentication systems currently used are easy, but only if ...

In this paper, we propose a handover authentication mechanism, called the handover key management and authentication scheme (HaKMA for short), which as a three-layer authentication architecture is a new version of our previous work, the Diffie-Hellman-PKDS-based authentication method (DiHam for short), improving its key generation flow and adding a handover authentication scheme to respectively...

In GSM-WLAN heterogeneous networks, the authentication efficiency is one of the drawbacks for message transaction and processing in the RADIUS server. This paper proposed two fast authentication schemes, based on the EAP-SIM mechanism, to improve the authentication efficiency by balancing the message transaction loads and processing loads among the RADIUS server and individual APs. In this pape...

Backup authentication systems verify the identity of users who are unable to perform primary authentication—usually as a result of forgetting passwords. The two most common authentication mechanisms used for backup authentication by webmail services, personal authentication questions and email-based authentication, are insufficient. Many webmail users cannot benefit from email-based authenticat...

E-Learning enables the users to learn at anywhere at any time. In E-Learning systems, authenticating the E-Learning user has security issues. The usage of appropriate communication networks for providing the internet connectivity for E-learning is another challenge. WiMAX networks provide Broadband Wireless Access through the Multicast Broadcast Service so these networks can be most suitable fo...

With the increasing number of mobile and wireless networks that are deployed, the handovers between these systems take place more often. In order to provide end-users with uninterrupted access to services, support for fast handover is essential. One of the prerequisites of a fast-handover is transparent end-user authentication. In this paper we address end-user authentication at network level. ...
