Abstract：P2P live video systems are widely used in today's Internet. Compared with eMule/BitTorrent and other traditional P2P file-sharing systems, a P2P live video system has higher requirements on real-time data, which becomes vulnerable weakness. Delay attack, with strong concealment, is potentially lethal for large P2P video broadcasting systems. Theoretical security threats of popular P2P live video systems were analyzed to propose three types of delay attack based on Eclipse attack, No-Offer attack, Delay-Chunk attack, and No-Chunk attack, with a high-availability defense strategy against delay attack being developed. Experiments were made on PlanetLab based on PeerStreamer, which proves the impact of delay attack and the effectiveness of the developed defense strategy.
