Based On The Security Of The Streaming Media Downloaded Transparently

8010 R&D laboratory of UESTC have developed a P2P living streaming system before called Transparent Download System, which already have a good performance in some Intranet.To address this limitation, this paper proposes a secure and high-performance streaming system called SecureTransfer, which is the improving vision of Transparent Download on secure and scalability issue.To reduce the secure overhead of whole system, we just apply our security scheme on base layer. Security management of base layer includes two components: user authentication scheme and key management scheme.The main properties of presented secure systems include:1) A novel PSP media streaming architecture, which utilizes the best feature of scalable coding, application layer multicast and P2P, thus possessing the unprecedented capability of addressing all the four critical issues in media streaming, i.e., security, QoS, scalability, and heterogeneity;2) A security management mechanisms based on base layer, which reduce the secure overhead of whole system greatly;Moreover, the analysis shows the efficiency, scalability and robustness of given schemes in P2P live streaming systems, named "Secure Streaming".
