在传感器网络中，确保匿名性是一个主要的安全目标。使用流量分析，攻击者可以通过将数据流模式与事件位置/活动区域相关联来损害网络功能。在本文中，我们提出了一种新的分层匿名通信协议，隐藏节点的位置和模糊的事件区和数据流之间的相关性从窥探对手。我们通过引入一个新的匿名性度量：曝光度指数来量化我们的协议的匿名性强度。我们的协议的目的是提供灵活的匿名性和通信延迟开销之间的权衡。
Ensuring anonymity in sensor networks is a major security goal. Using traffic analysis, the attacker can compromise the network functionality by correlating data flow patterns to event locations/active areas. In this paper we present a novel hierarchical anonymous communication protocol that hides the location of nodes and obscure the correlation between event zones and data flow from snooping adversaries. We quantify the anonymity strength of our protocol by introducing a new anonymity metric: Degree of Exposure Index. Our protocol is designed to offer flexible tradeoffs between degree of anonymity and communication-delay overhead.
