Anonymity: Securing User Privacy on the Internet

今天，万维网是电子商务(包括电子广告、电子银行等)的基础。不幸的是，万维网并没有很好地支持匿名性(在流行的媒体中被称为“隐私”)。虽然在机械社会中，橱窗购物者不需要表明自己的身份，但当他们使用万维网时，他们隐含或明确地(在一定程度上)这样做。“隐私”问题可能会限制互联网的发展和使用。保证匿名的最新技术只能提供较弱的安全性，或者太昂贵而无法使用，或者完全不切实际。此外，一些协议已经被打破。目标是：1.重新访问和(加密)分析现有协议，2.研究更有效的协议以实现健壮的匿名通信，3.开发即使在内部人员试图打破匿名性或试图干扰匿名通信时也能保证匿名性的协议，4.在不危及通信的匿名性的情况下解决cookie的用户友好方面，5.增强非常安全(称为无条件安全)的匿名通信协议，6.研究有限匿名性。

Today the World Wide Web is the foundation of e-commerce (including, e-advertisement, e-banking, etc.) Unfortunately, the World Wide Web does not offer good support for anonymity (called "privacy" in the popular press). While in a mechanical society window shoppers do not need to identify themselves, they implicitly or explicitly do so (to a certain extend) when using the World Wide Web. "Privacy" concerns may limit the growth and the use of the internet.The state of the art techniques to guarantee anonymity only provide weak security, or are too expensive to be used, or are completely impractical. Moreover, some protocols have been broken. The goals are:1. to revisit and to (crypt) analyze existing protocols,2. to study more efficient protocols to achieve robust anonymous communication,3. to develop protocols to guarantee anonymity even when insiders are trying to break the anonymity, or trying to disrupt the anonymous communication,4. to address the user-friendly aspect of cookies, without endangering the anonymity of the communication,5. to enhance very secure (called unconditionally secure) protocols for anonymous communication,6. to study limited anonymity.
