Security Issues for P2P-Based Voice- and Video-Streaming Applications
نویسنده
چکیده
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 P2Pbased voice and video streaming applications.

A Novel Caching Strategy in Video-on-Demand (VoD) Peer-to-Peer (P2P) Networks Based on Complex Network Theory
The popularity of video-on-demand (VoD) streaming has grown dramatically over the World Wide Web. Most users in VoD P2P networks have to wait a long time in order to access their requesting videos. Therefore, reducing waiting time to access videos is the main challenge for VoD P2P networks. In this paper, we propose a novel algorithm for caching video based on peers' priority and video's popula...
