Modern wireless computing devices raise privacy concerns by leaking information that can be used to track and profile users. These privacy concerns are inherent to the low-level design of network and link-layer protocols and are, therefore, not addressed by the traditional approach of encrypting messages to ensure that their contents remain confidential. This project studies the question of how to protect user privacy in the context of a future Internet with rich connectivity to these wireless computing devices. The research focuses on designs that accomplish this without sacrificing the requirements for manageability and accountability.The research approach is to study existing systems such as 802.11 to characterize privacy threats and design improved network and link protocols that provide stronger privacy guarantees. Part of the project is to rethink names and addresses in their various forms to limit the disclosure of identity information only to trusted parties This includes names that conceal identity without compromising network functions, such as routing, that rely on them; name discovery and resolution protocols that do not reveal information across system layers.; techniques to detect implicit names exposed by end-points. Finally, the project also explores methods to expose the privacy status to users.Broader Impact: The combination of improving privacy and educating end-users about their privacy risks significantly and justifiably reduces the fears of Internet users. This makes the Internet a more widely accessible resource by allowing users to perform tasks, such as online-shopping, that they may not have been comfortable with before.

现代无线计算设备会泄露可用于跟踪和分析用户的信息，从而引起人们对隐私的担忧。这些隐私问题是网络和链路层协议的底层设计所固有的，因此，通过加密消息以确保其内容保持机密的传统方法无法解决这些问题。该项目研究的问题是如何在未来互联网的背景下保护用户隐私与这些无线计算设备的丰富连接。研究的重点是在不牺牲可管理性和责任要求的情况下实现这一目标的设计。研究方法是研究现有的系统，如802.11，以表征隐私威胁，并设计改进的网络和链路协议，提供更强的隐私保障。该项目的一部分是重新考虑各种形式的名称和地址，以限制仅向受信任方披露身份信息，这包括隐藏身份而不损害依赖于它们的网络功能（如路由）的名称；命名不跨系统层显示信息的发现和解析协议。检测端点暴露的隐式名称的技术。最后，该项目还探索了向用户公开隐私状态的方法。更广泛的影响：改善隐私和教育最终用户有关其隐私风险的结合显著和合理地减少了互联网用户的恐惧。这使得互联网成为一个更广泛的资源，允许用户执行任务，如网上购物，他们可能不习惯以前。
