Many applications in e-learning utilize wireless networks (WLAN) as a carrier for data and communication. These networks in their basic form are unsecured, protecting the communication is a pre-condition for using a WLAN for confidential contents. Many existing solutions either do not provide the necessary 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.
