论文摘要
车辆临时网络将流量信息从许多来源分布到许多目的地，都需要数据身份验证机制来检测用户的任何恶意行为，例如修改或重播攻击。在本文中，我们提出了一种新的数据汇总协议，该协议使用概率验证来检测此类攻击，以有效的方式进行后验尝试，并以最小的开销和延迟。该算法还包含基于根据需求创建的反应性组的附加安全机制，这确保了车辆产生值得信赖的信息。根据包括小规模的真实设备实现和NS2模拟的全面分析，这表明所提出的协议是可靠的。
Vehicular ad-hoc networks, where traffic information is distributed from many sources to many destinations, require data authentication mechanisms to detect any malicious behavior of users, such as modification or replay attacks. In this paper we propose a new data aggregation protocol that uses probabilistic verification to detect such attack attempts a posteriori in an efficient way, with minimal overhead and delay. The algorithm also contains an additional security mechanism based on reactive groups created on demand, which ensure a priori that vehicles generate trustworthy information. According to a comprehensive analysis including both a small-scale real device implementation and NS2 simulations, it is shown that the proposed protocol is robust.
