    <subfield code="a">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.</subfield>
