摘要
车载自组织网(vehicular Ad hoc networks,VANETs)中的车辆通过周期交互beacon实现信息共享,从而提高交通安全,然而VANETs无线网络特性系统易遭受多类攻击,特别是对beacon的传输攻击,即干扰beacon的传输,其严重影响VANETs的安全性能。为此,建立车队platooning模型,提出实时检测干扰beacon传输的攻击方案。该方案首先将节点beacon传输时间分为相互独立的时隙,并依据此时隙将车辆分为不同的群,使得群间的beacon彼此不碰撞,从而降低beacon被干扰的概率。最后,针对两类攻击类型进行仿真。仿真结果表明,提出的检测攻击方案具有良好的性能,初始检测时间小于150 ms,平均检测率不低于0.9。在两个干扰者的情况下,漏警率小于0.15,平均的虚警率小于0.2。
The cooperation between the vehicles in the VANET is achieved by the frequent exchange of periodic broadcast messages carrying information on vehicle position and velocity, which is referred to as beacons, which is in favor of improving the security of VANET. However, the nature of medium in wireless networks makes it easy for adversary to launch a attack, especially jamming the beacon transmission, which seriously affects the performance of VANET. Therefore, this paper constructed the model of platooning, and proposed a real-time detection jamming-beacon-transmission scheme. In this scheme, it divided time for transmission beacon into independent time slot. In the way that beacons from different groups never collided, it reduced the probability of interference with beacon. Finally, in view of the two types of attack types were simulated. Tile simulation results show that the proposed detection attack scheme has good performance, the initial detecting time is less than 150 ms, the average detection rate is not less than 0.9. In the case of two jammers, FNR is less than 0.15, the average FPR is less than 0.2.
