安全和隐私问题被认为是使用移动的应用程序的组织和个人最关心的两个问题。在本文中，我们试图解决延迟容忍网络（DTNs）中的匿名通信。虽然许多不同的匿名路由协议已被提出的ad hoc网络，据我们所知，只有洋葱为基础的路由的变种已量身定制的DTN。由于每种类型的匿名路由协议都有其优点和缺点，因此没有一种用于DTN的匿名路由协议可以适应不同级别的安全要求。在本文中，我们首先设计了一套匿名路由协议的DTN，称为匿名流行病和基于区域的匿名路由，在原来的匿名路由协议的基础上，为ad hoc网络。然后，我们提出了一个框架的匿名路由（FAR）的DTNs，其中包括所有上述协议。通过调整其参数，所提出的FAR能够优于洋葱为基础的，匿名的流行病，和基于区域的路由。此外，数值分析的可追踪率和节点匿名模型。广泛的模拟使用随机生成的图以及真实的痕迹进行证明，适当的参数设置，我们的FAR优于所有现有的匿名路由协议的DTNs。
Security and privacy issues are considered to be two of the most significant concerns to organizations and individuals using mobile applications. In this paper, we seek to address anonymous communications in delay tolerant networks (DTNs). While many different anonymous routing protocols have been proposed for ad hoc networks, to the best of our knowledge, only variants of onion-based routing have been tailored for DTNs. Since each type of anonymous routing protocol has its advantages and drawbacks, there is no single anonymous routing protocol for DTNs that can adapt to the different levels of security requirements. In this paper, we first design a set of anonymous routing protocols for DTNs, called anonymous Epidemic and zone-based anonymous routing, based on the original anonymous routing protocols for ad hoc networks. Then, we propose a framework of anonymous routing (FAR) for DTNs, which subsumes all the aforementioned protocols. By tuning its parameters, the proposed FAR is able to outperform onion-based, anonymous Epidemic, and zone-based routing. In addition, numerical analyses for the traceable rate and node anonymity models are built. Extensive simulations using randomly generated graphs as well as real traces are conducted to demonstrate that given appropriate parameter settings, our FAR outperforms all the existing anonymous routing protocols for DTNs.
