The invention aims to provide a revocable vehicle position ciphertext matching method based on the Internet of Vehicles. The method comprises the following steps that: a vehicle encrypts a vehicle position by using a public key to obtain a ciphertext; the vehicle sends a ciphertext to the traffic management center; and the traffic management center obtains the number of vehicles running in T minutes of the current street according to the matching condition of the position ciphertexts sent by all the vehicles in T minutes of the current street, judges the congestion condition according to the number of the vehicles, and dynamically adjusts the parameters of the traffic signal lamp. According to the invention, the RPC-MPKET technology is utilized, and the vehicle position data can be safely sent to an intelligent traffic signal system. In addition, if the vehicle wants to hide its past route, it can cancel its ciphertext matching authorization to the traffic control center.

    本发明的目的是提供一种基于车联网的可撤销的车辆位置密文匹配方法,该方法包括:车辆采用公钥对车辆位置进行加密得到密文;车辆对交管中心发送的密文;交管中心根据当前街道T分钟内所有车辆发送的位置密文匹配情况得出当前街道T分钟内行驶的车数量,根据车辆数量判定拥堵情况动态调整交通信号灯的参数。本发明利用RPC‑MPKET技术,可以安全地将车辆位置数据发送到智能交通信号系统。此外,如果车辆想要隐藏其过去的路线,它可以撤销其对交管中心的密文匹配授权。
