The invention discloses a credible and privacy protection intelligent traffic light method and system based on a V2X technology. The method comprises the following steps: initializing the system; performing vehicle registration; the trusted authority TA verifying whether the vehicle identity is legal, and issuing a reputation certificate if the vehicle identity is legal; sending a request messageto the traffic light by a vehicle about to pass through the intersection; the traffic light performing vehicle scheduling according to the received request message; the traffic light judging whether the actual behavior of the vehicle is consistent with the vehicle request; and the trusted authority TA updating the reputation table. According to the invention, the traffic signal lamps can be dynamically adjusted according to the traffic condition of the intersection, and the display and duration are changed, so that the traffic jam is effectively reduced. The safety of the privacy information is protected while the trustworthiness of the information provided by the vehicle is ensured, the traffic light system and the vehicle are prevented from being attacked by attackers as much as possible, and the vehicle privacy safety in the intelligent vehicle driving process and the safety and trustworthiness of the information received by the traffic light system are ensured.

    本发明公开了一种基于V2X技术的可信、隐私保护的智能红绿灯方法及系统,方法包括以下步骤:系统初始化;车辆注册;可信机构TA验证车辆身份是否合法,如果合法则颁布声誉证书;即将通过路口的车辆向红绿灯发送请求消息;红绿灯根据收到的请求消息进行车辆调度;红绿灯判断车辆的实际行为是否与车辆请求一致;可信机构TA更新声誉表。本发明能够根据路口交通状况动态地对交通信号灯进行调整,改变显示和时长,从而有效减少交通拥堵的发生;在保障车辆提供的信息真实可信的同时对隐私信息的安全性予以保护,尽可能保证红绿灯系统和车辆免受攻击者的各类攻击,确保在智能汽车驾驶过程中的车辆隐私安全和红绿灯系统所接收的信息安全可信。
