Securing Wireless Networks in a University Environment

Jochen Eisinger, Peter Winterer and Bernd Becker

Many applications in eLearning utilize wireless networks (WLAN) as a carrier for data and communication. These networks in their basic form are insecure, protecting the communication is a pre-condition for using a WLAN for confidential contents. Many existing solutions either do not provide the neccessary security or fail when employed with large user bases. The IPSec based solution developed at the Faculty of Applied Science of the University of Freiburg provides a high level of security, and by using digital X.509 certificates the problem of administrating a large user base is solved as well.
