Security Issues for P2P-based Voice- and Video-Streaming Applications

Abstract. P2P computing offers a new interesting field for security re-searchers. Being highly distributed and lacking centralised, trusted enti-ties for bootstrapping security mechanisms, these systems demand novel approaches for decentralised security solutions. Recently, a new class of P2P-applications has arisen: P2P-based voice and video streaming systems. The properties of these novel applications impose new, interesting security challenges which have only been started to be addressed by researchers. This paper presents a summary of existing work in the area, derives and discusses open research problems, and finally outlines approaches towards potential solutions for securing P2P-based voice and video streaming applications.
