Floating vehicle-based traceability vehicle self-networking communication privacy protection method

Abstract

The invention discloses a floating vehicle-based traceability vehicle self-networking communication privacy protection protocol, which is characterized in that a floating vehicle is used as a mobile RSU (Remote Subscriber Unit), a floating vehicle auxiliary grouping technology is adopted, the floating vehicle F adopts V2V communication, vehicles running in the same direction in an effective communication radius are united to spontaneously form a group, F is used as a group leader and is in charge of authorizing the validity of the vehicles and maintaining a group key and a specified group parameter; and F and all members respectively have a one-to-one secret channel negotiated by anonymous certificates issued by an authentication center (TA), the members sends messages to be broadcasted to the F by using the channels, the F is subjected to the message anonymilization and encrypted by using a group key-based symmetric encryption algorithm and then forwarded to other members or other groups, and when the messages are disputed, under the authorization of the TA, the real identity of the vehicle generating the messages can be accurately located.

Description

technical field [0001] The invention belongs to the field of safety protection of vehicle ad hoc networks, and in particular relates to a method for protecting communication privacy of a traceable vehicle ad hoc network based on floating vehicles. Background technique [0002] With the large-scale and high-frequency use of vehicles in modern society, the establishment of a vehicle ad hoc network to form the basic environment of the "smart car" network can effectively improve the driving experience, relieve traffic pressure, and reduce traffic accidents; but on the other hand, There is also an urgent need to improve the safety of vehicles in driving conditions, including security identity authentication and privacy protection. [0003] Since the vehicle ad hoc network needs to authenticate the vehicle object that provides the information and protect the integrity of the information it provides, but at the same time of authentication, the vehicle user will face the danger of p...

AI Technical Summary

Problems solved by technology

These solutions solve the security and privacy issues of some vehicular ad hoc networks from a certain aspect, but they all have their own defects or problems to be solved, and the solutions are not mature and practical enough.

[0005] The importance of the security and privacy protection of the vehicle ad hoc network is self-evident, but while studying the privacy protection of the vehicle, it inevitably brings another problem, how to solve the problem when necessary, such as after a dispute or a safety accident , with the participation of authoritative departments or law enforcement departments, effectively trace the true identity of the signer of the message
