考虑一个标准的多跳无线电网络,其中节点互相传递消息.虽然消息的内容可能敏感,因此加密,但两个无线电通信的事实可以泄露有关来源的物理位置和目的地的物理位置的敏感信息。

Abstract

Consider a standard multi-hop wireless radio network in which nodes relay messages for one another. While the contents of messages may be sensitive and thus encrypted, the very fact that two radios communicated can leak sensitive information about both the physical location of the origin and the physical location of the destination. We investigate the trade-off between protecting the privacy of a user's current location and the privacy of their location of interest, and how the user should choose dummy destinations to obfuscate their queries.
