We provide sender anonymity for public service connection and file sharing. No modification to the underlying p2p networks is needed. Our system achieves co-existence of anonymous file sharing and normal structured p2p communication. We also proposed three routing methods with various performance and degrees of anonymity for different purposes. Analytic analysis show that our system outperform existing systems.目錄 Chapter 1 Introduction 1 1.1 Privacy 1 1.2 Anonymity in P2P Networks 2 1.3 Using Structured P2P Networks 2 1.4 Thesis Organization 3 Chapter 2 Related Work 5 2.1 History 5 2.2 Anonymity 6 Chapter 3 System Description 10 Chapter 4 Routing Methods 14 4.1 Relay by Routing 15 4.2 Relay by Neighbor 17 4.3 Hybrid Method 18 4.4 Path Building Strategy 20 4.5 Receiver Anonymity 20 Chapter 5 System Analysis 22 5.1 Security Analysis 22 5.2 Performance Analysis 26 5.2.1 Relay by Routing 26 5.2.2 Relay by Neighbor 29 5.3 Comparisons with Previous Researches 31 Chapter 6 Conclusions 36360485 bytesapplication/pdfen-US匿名性同儕網路隱私保護匿名網路網路安全anonymitypeer-to-peer networksprivacyanonymous networksnetwork securitythesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/58421/1/ntu-96-R94944032-1.pdf
