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