Abstract: This paper addresses the design issues and the security concept of the digital lecture board which is an enhanced whiteboard tailored to the specific needs of collaborative types of work, for instance, in computer-based distance education. The development of the digital lecture board emerged from our experience with sychronous, computer-based distance education in the TeleTeaching projects of the University of Mannheim. For almost two years, we have been using video conferencing tools fpr transmitting lectures and seminars. These tools prove to be far from optimal for this purpose since they are not powerful enough to support team work, they are not flexible enough for the use of media, and somewhat difficult to handle by non-experts. Security issues such as authentication, secure key exchange, and fast symmetric encryption are almost completely neglected, even though security is extremely important to allow for confidential, private sessions and billing. We discuss shortcomings of existing video conferencing tools and describe features, we had in mind while designing the digital lecture board. We then present our security concept which is a user-oriented approach taking into account the specific security requirements of different user groups. We also cover implementation issues of the current prototype.
