Proposed model for e-exam availability in WLAN environment

E-exam is often used to evaluate the success of learning process on e-learning system. To maintain the honesty, fairness and accountability of e-exam, security system should be pursued to anticipate a variety of fraud or any threat that may occur during the process of e-exam. This paper identifies the role and type of technologies for securing e-exam. Study on e-exam security that emphasizes the aspects of authenticity, confidentiality and integrity has been widely found. This paper also proposes an e-exam security model that emphasizes the aspects of availability for implementation in wireless environment especially at Wireless Local Area Network (WLAN) environment. As well known that the quality of radio signal is affected by many factors, it affects the availability of IT services over wireless link. Therefore, the model is proposed to be able for examinees to complete their examination although there has been a connection or information access problem during the examination.
