匿名網路之架構與金鑰管理

Abstract

在現代的生活中，網路幾乎是不可或缺的一部分，許多傳統的工作或娛樂以及一般日常生活行為，都越來越仰賴網路科技，因此，對於網路的安全性，也越來越受到重視。在目前的安全技術中，針對網路傳輸封包的內容已經能提供相當程度的保護，但是仍然有其他的威脅存在。

在目前的網路架構下，即使不知道傳輸封包的內容，只要查探封包中一些不可隱藏的資訊，仍然會透露出重要的訊息。藉由封包中註明的來源和目的網路位置，可能會洩漏出通訊雙方的真實身份，因而造成隱私洩漏的危險。

在這篇論文中，我們提出一個匿名網路系統的設計，針對網路傳輸的隱私性加以保護，具有足夠的安全和效率，當使用者數量增加時，依然能維持良好的運作。

In modern life, Internet is so important that almost part of many traditional work or entertainment and daily life, in general, are increasingly dependent on it. Hence, network security has been more and more important. In current security technology, network transmission against the contents of the packet can already provide a considerable degree of protection, but there are still exists other threats.

In current network architecture, even if the contents of packet are not known by others, the progress of transmission is still leaked out some information, as long as searching for the information that can’t be hidden, will reveal important message. Observing the packet header, the source and destination of Internet location, it may leak out the identity of both parties in communication. Privacy leakage may result in dangerous.

In this paper, we represent an anonymous network system, it provides protection of transmission privacy, keeps adequate safety and efficiency, when the scale increases, still maintain well operation.
