摘要

這篇論文提出了一個在結構性同儕網路上提供匿名性的彈性方案。這套系統可以同時在對於外部的公開服務以及內部的檔案分享上提供發訊息發者的匿名性，在此同時並不需要對於原來的結構性同儕網路進行修改。使得系統可以達到匿名檔案分享與原來的結構性同儕網路同時使用之能力。我們也提出了三種不同的路由方式，各有不同的效能以符合各種情況的需求。分析結果亦顯示我們的系統較現有系統擁有更好的效能。

This thesis describes a flexible scheme for providing anonymity in structured peer-to-peer networks. 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.
