CST member Matthias Wählisch has been invited to participate in the Dagstuhl Seminar "Secure Routing for Future Communication Networks". To advance routing security, a number of significant research problems need to be addressed, which is the goal of this seminar. The first objective is to facilitate brainstorming and exchange of ideas among experts working in different areas and types of secure networking, leading to an improved understanding of the different aspects of secure routing. The second objective is to identify the most important research challenges and to devise a roadmap towards addressing urgent issues. Through the seminar, we are hoping to open up new avenues of research in the area of routing security.
