Design and Implementation of Secure Distributed Examination System

The distributed examination system based on the separation of examination sites separates the examination sites from the examination center. Examination sites are also separated from each other. The examination center’s program files that are responsible for the personnel management, exam database management, randomly generating papers and assigning papers are deployed on the central server in an office. The codes of examination sites can be deployed on any PC to be in charge of downloading exam papers, examination management, marking the papers and uploading exam results. The communication between the examination center and the examination sites is carried out via the Internet. In this paper, we research the security of the distributed examination system and implement a secure distributed examination system which can guarantee a safe communication between the examination center and examination sites by means of Internet security, such as identity authentication, data encryption and data integrity authentication.
