There are many famous applications, such as YouTube, ImTV, and Google Video. Besides, the VoD services supplied by ISP’s are also widely used. But these applications use the traditional broadcast, the number of membership are restricted by computation power and bandwidth. There are many peer-to-peer multimedia streaming researches recently, and some applications are on-lined. For example, there are PPStream, PPLive, TVAnts, and SopCast. But all these applications and protocols lack for membership management and stream protection. This thesis propose a new multimedia streaming protocol on overlay multicast network.1 Introduction 1 1.1 Internet Video Delivery 1 1.2 Cryptography 2 1.3 Secure Group Communication 4 1.4 Related Work 7 1.5 Outline of the Following Chapters 7 2 Secure Multicast Streaming 8 2.1 Secure Streaming 8 2.2 Basic Concept 8 2.3 A Satisfied Secure Key Management 9 2.4 Term Definition 9 2.5 Architecture 11 3 Membership Management 17 3.1 Concept of Multiple-Agent Mechanism 17 3.2 Term Definitoin 18 3.3 How to Join/Leave Multicast Group 18 3.4 Membership Management Agent 20 3.5 Summary of the Membership Management 21 4 Discussion 23 4.1 Load of Content Provider 23 4.2 Different Re-keying Strategy 23 4.3 Security 24 5 Conclusion 25 Bibliography 266084927 bytesapplication/pdfen-US網際網路多媒體多媒體串流群播覆蓋網路安全的多媒體串流Internet multimediaMultimedia streamingOverlay multicast networkSecure multimedia streamingthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/54012/1/ntu-95-R91922073-1.pdf
