Security Enhancement Using Cache Based Reauthentication in WiMAX Based E-Learning System.

Rajagopal C, Bhuvaneshwaran K - ScientificWorldJournal (2015)

Bottom Line: In E-Learning systems the users must be forced to perform reauthentication to overcome the session hijacking problem.The reauthentication of users introduces frequent delay in the data access which is crucial in delaying sensitive applications such as E-Learning.Even though the cache mechanism requires extra storage to keep the user credentials, this type of mechanism reduces the 50% of the delay occurring during reauthentication.

ABSTRACT
WiMAX networks are the most suitable for E-Learning through their Broadcast and Multicast Services at rural areas. Authentication of users is carried out by AAA server in WiMAX. In E-Learning systems the users must be forced to perform reauthentication to overcome the session hijacking problem. The reauthentication of users introduces frequent delay in the data access which is crucial in delaying sensitive applications such as E-Learning. In order to perform fast reauthentication caching mechanism known as Key Caching Based Authentication scheme is introduced in this paper. Even though the cache mechanism requires extra storage to keep the user credentials, this type of mechanism reduces the 50% of the delay occurring during reauthentication.
