Abstract

Even as wireless networks create the potential for access to information from mobile platforms, they pose a problem for privacy. In order to retrieve messages, users must periodically poll the network. The information that the user must give to the network could potentially be used to track that user. However, the movements of the user can also be used to hide the user's location if the protocols for sending and retrieving messages are carefully designed. We have developed a replicated memory service which allows users to read from memory without revealing which memory locations they are reading. Unlike previous protocols, our protocol is efficient in its use of computation and bandwidth. We show how this protocol can be used in conjunction with existing privacy preserving protocols to allow a user of a mobile computer to maintain privacy despite active attacks.<>
在移动计算机网络中保护隐私
尽管无线网络创造了从移动平台获取信息的可能性,但它们也带来了隐私问题。为了检索消息,用户必须定期轮询网络。用户必须提供给网络的信息可能被用来跟踪该用户。然而,如果仔细设计发送和检索消息的协议,用户的移动也可以用来隐藏用户的位置。我们已经开发了一个复制内存服务,允许用户从内存中读取,而不会显示他们正在读取的内存位置。与以前的协议不同,我们的协议在计算和带宽的使用上是高效的。我们展示了该协议如何与现有的隐私保护协议结合使用,以允许移动计算机的用户在受到主动攻击时保持隐私。
