随着人们生活水平的不断提高,车辆已经成为人们不可缺少的代步工具。城市车辆的增加,造成了城市交通堵塞的状况,对人们的生活以及工作带来不便。基于信息中心网络的车联网已经进入城市车辆动态路径的规划当中,而在目前的车联网中,对于路况信息的传递缺少一定的信任机制,这就容易导致不必要的麻烦。本文主要从车联网安全和以可信的数据为基础的路况消息信任模型来阐述路况消息的真实可靠性,并推算出确切值。本实验的结果表明,通过本数据模型能够有效避免和减少虚假、恶意消息的侵扰,提升车辆在行驶过程中的安全性和效率。同时其特点也是比较明显的,时间的复杂度比较低,不会利用其它信息干扰真实判断。
With the continuous improvement of people’s living standards, vehicles have become an indispensable means of transport for people. The increase of urban vehicles has caused the traffic jam in the city and brought inconvenience to people’s life and work. Vehicle networking based on information center network has entered the planning of urban vehicle dynamic path. However, in the current car networking, there is a lack of certain trust mechanism for the transmission of traffic information, which easily leads to unnecessary trouble. In this paper, the reliability of traffic information is expounded mainly from the safety of car network and the trust model of traffic information based on credible data, and the exact value is deduced. The results of this experiment show that the data model can effectively avoid and reduce false and malicious messages, and improve the safety and efficiency of vehicles during driving. At the same time its characteristics are more obvious, the time complexity is relatively low, will not use other information to interfere with the true judgment.
