A traffic accident collaborative authentication processing and traceability system based on blockchain technology

Abstract

The invention discloses a traffic accident collaborative authentication processing and traceability system based on block chain technology. Including steps: 1. System initialization process. Including CA public and private key initialization, identity registration of RSU in the whole network. 2. The process of traffic accident information collection and authenticity judgment. The vehicle periodically broadcasts messages to neighboring vehicles and the local RSU. If an accident occurs, the EDR in the vehicle will get an immediate response and set the header of the accident message to Accident. Neighboring vehicles detect whether the header of the received message is Accident, and if so, trigger the driving recorder to take pictures in real time, and use the collaborative authentication based on neighboring vehicles and local RSU to determine the authenticity of the accident. 3. The process of uploading accident information to the chain. Including the realization of consensus between RSUs, block verification and other work. The local RSU broadcasts the encrypted information to other RSUs in the entire network. The RSUs in the entire network use the improved PoW consensus mechanism to quickly upload the accident information to the chain, and at the same time, the local RSU encrypts the accident information and uploads it to the cloud node. 4. Handling of traffic accidents. The cloud computing node decrypts the accident message, and broadcasts the accident information to the RSU under the jurisdiction to realize the accident reminder of the whole network vehicles. At the same time, cloud computing nodes and RSU nodes cooperate with the search to trace the source of traffic accidents.

Description

technical field [0001] The invention belongs to the technical field of Internet of Vehicles, and in particular relates to a traffic accident collaborative authentication processing and traceability system based on block chain technology. Background technique [0002] Dealing with traffic accidents has always been a headache. For real traffic accidents, how to quickly respond to the accident scene (emergency command, traffic guidance, etc.), quickly judge the accident, and hold the vehicle responsible have become the three major problems for the traffic law enforcement department. Traditional methods such as checking surveillance camera information, vehicle driving recorder, EDR (event data recorder), and on-site clue investigation and certification have the following disadvantages: [0003] 1. The traditional method only focuses on the judgment and handling of the accident and ignores the precious time on the scene when the traffic accident occurs. If the vehicles nearby at...

Problems solved by technology

[0003] 1. The traditional method only focuses on the judgment and handling of the accident and ignores the precious time on the scene when the traffic accident occurs. If the vehicles nearby at the time of the accident have no knowledge of the surrounding traffic events, traffic jams will occur in light cases, and traffic jams will occur in severe cases. serial traffic accident

[0004] 2. The quality of video information, the reliability of event data, and the man-made or natural destruction of effective clues on the scene will all hinder the investigation of accidents

However, this method has the following shortcomings: First, traffic accidents in this method need to passively rely on the traffic department as the center for mining, which not only brings a lot of computing and processing pressure to the traffic department, but also uses the general Hong technology and delay-tolerant network technology cannot support the low-latency requirements in the Internet of Vehicles environment; second, this method only focuses on the collection of traffic accidents, and cannot handle the accident scene efficiently and properly at the first time when the accident occurs To avoid greater loss of personnel and property; third, there is no encryption or protection measures in the process of information collection, which may easily lead to fraudulent use or tampering of information during transmission, and eventually lead to unequal information among all parties. lead to disputes in the process
