为减少车载自组网中的各种入侵行为对司机和乘客的生命财产安全带来的损失,提出了一种基于不同交通场景的混合式入侵行为检测机制(mixed intrusion detection scheme,MIDS)。当车辆在同一道路上行驶时,选择基于消息一致性的MIM(message integrity method)方法,否则使用VOTE方法,在网络条件允许的情况下,可以申请发送方发送相关的场景信息证明警告消息的真实性。实验结果表明,该方法具有较低的通信时延和较高的检测率,有效克服了现有方法的局限性,能够检测多种入侵行为。
In order to reduce the loss of lives and property of drivers and passengers caused by various intrusion behaviors in MANET, a hybrid intrusion detection scheme (MIDS) based on different traffic scenarios is proposed. When the vehicle is driving on the same road, select MIM (message integrity method) based on message consistency, otherwise use VOTE method, under network conditions, apply for the sender to send the relevant scene information to prove the trueness of the warning message Sex. The experimental results show that this method has lower communication delay and higher detection rate, effectively overcomes the limitations of the existing methods and can detect multiple intrusion behaviors.
