Security issues for P2P-based voice- and video-streaming applications

Abstract

P2P computing offers a new interesting field for security researchers. Being highly distributed and lacking centralised, trusted entities 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. © IFIP International Federation for Information Processing 2009.
