The Design And Implementation Of Secure Information System For Teaching Administration

Educational informatization and e-campus are the core and basis as well as the very important content of teaching administration in universities and institutes. The rapid development of the computer technology and Internet increase the speed of network based teaching administration system. This system which is based on the campus network with one or more point attached to the Internet implements the management centralized, the operation dispersed and the information communicated and makes the traditional teaching administration developed into the automation, computerization and office automatization. At the same time, the problem on security of teaching administration system also emerges and is becoming serious. The thesis researches the technology of network security, mainly compares and analyzes firewall, intrusion detection, and the PKI-based technology of authentication, digital signature and DRM. After that, the author constructs the scheme of Secure Information System for teaching administration, gives the secure model of it, and expounds the methods and technologies to implement it, and at last realizes it.This secure information system consists of two main parts. In the network secure part, the thesis pays attention to the network secure technologies and secure productions, then the firewall and IDS are used to protect security of the network. While having introduced the PKI, the thesis uses digital authentication to implement identification authentication; the technology based on digital signature ensures the data security; the digital authentication and DRM are mixing used to perform the management of digital resource copyrights.This secure information system has highly security. With the widely prevalence of teaching administration system, teaching administration system which combines this secure information system would be more practicability and develop rapidly to a certainty.
