Design and Analysis of Data Security Protocol in Online Examination System

Abstract

Examination is an evaluation step of learning process, aimed at measuring level of success of the process. Conventional examination system with paper media is effective and efficient with few test participants, centralized location and flexible time. However, it is not effective with a large number of participants, scattered locations, and simultaneous time, like the National Final Examination (Ujian Akhir Nasional – UAN) and Public University Entrance National Selection (Seleksi Nasional Masuk Perguruan Tinggi Negeri – SNMPTN). Therefore, a reliable, fast and accurate examination system, utilizing Internet is required. The alternative method is an online examination system using computer and internet connection. The system requires availability of clear and accurate data which can only be accessed by authorized person. The common technique to secure data within internet media is cryptography. It is used to keep the information security of the data, so that unauthorized person cannot access it. The research is conducted to produce a protocol design that can be used to secure data relevant to the online examination system. The research method used security basic need analysis and Security Life Cycle (Bishop 2003). The data security protocol design is implemented by Power Builder 10.0 Build 4500 programming language and library java of Java Cryptographic Extension (Weiss 2003). The result is data security protocol framework that conform to the security requirement of the online examination system.
