Embodiment Construction

[0052] The technical solutions of the present invention will be described in detail below, but the protection scope of the present invention is not limited to the embodiments.

[0053] Such as figure 1 As shown, there are three kinds of participants involved in a kind of reputation system-based 5G Internet of Vehicles fast message authentication method of the present invention, namely Trusted Authority (TA), Global Reputation Center (GRC), Roadside Base Station (BS) under 5G environment ) and a vehicle V equipped with an OBU i . With the wireless communication capability provided by OBU, the vehicle can communicate with TA and other vehicles.

[0054] Such as figure 2 As shown, a kind of reputation system-based 5G Internet of Vehicles fast message authentication method of the present invention comprises the following steps:

[0055] (1) Preparation process, TA initialization, vehicle registration and user login;

[0056] (2) During the communication process, the vehicle ...

Abstract

The invention discloses a 5G vehicle networking fast message authentication method based on a reputation system, which comprises the steps of TA initialization, vehicle registration, user login, vehicle publishing traffic information, message authentication, reputation management, updating of pseudonym and trustworthiness certification and the like. The invention uses a reputation system to improve the reliability of messages, because vehicles with reputations below the threshold cannot obtain from the TA the trustworthy proof required to participate in the communication, the 5G vehicle networking communication model in the invention is no longer limited to the mandatory assumption that the roadside base station is completely trusted or has been fully deployed, only the 5G base station isneeded to assist in transmitting the message in the vehicle networking, in addition, the signature part in the invention adopts the operation based on the elliptic curve cryptography and supports thebatch authentication of the message, so the calculation is low in transmission cost and the overall message authentication efficiency is higher.

Description

technical field [0001] The invention belongs to the communication security technology of the Internet of Vehicles, and in particular relates to a fast message authentication method for the 5G Internet of Vehicles based on a reputation system. Background technique [0002] At present, many countries are investing in the development and application of 5G. As an emerging technology, 5G has the remarkable characteristics of high speed, low latency, wide coverage, and support for D2D communication, bringing huge opportunities to the mobile Internet industry, especially the Internet of Vehicles. [0003] The so-called Vehicle Networking (VANETs) is that many different types of vehicles communicate with adjacent vehicles through the on-board unit (OBU) installed in the wireless network environment, thus forming a distributed self-organizing network. Vehicles periodically broadcast information about road and vehicle status, and two main applications are realized through information...
