Secured Session Based Profile Caching For E-Learning Systems Using Wimax Networks release_ltjvm7xfynhivfavfths2vn34m

Abstract

E-Learning enables the users to learn at anywhere at<br> any time. In E-Learning systems, authenticating the E-Learning user<br> has security issues. The usage of appropriate communication<br> networks for providing the internet connectivity for E-learning is<br> another challenge. WiMAX networks provide Broadband Wireless<br> Access through the Multicast Broadcast Service so these networks<br> can be most suitable for E-Learning applications. The authentication<br> of E-Learning user is vulnerable to session hijacking problems. The<br> repeated authentication of users can be done to overcome these<br> issues. In this paper, session based Profile Caching Authentication is<br> proposed. In this scheme, the credentials of E-Learning users can be<br> cached at authentication server during the initial authentication<br> through the appropriate subscriber station. The proposed cache based<br> authentication scheme performs fast authentication by using cached<br> user profile. Thus, the proposed authentication protocol reduces the<br> delay in repeated authentication to enhance the security in ELearning.
