Problems solved by technology

However, there are still some security problems in the current Internet of Vehicles authentication protocol, ignoring the security threats brought about by the improvement of hardware and communication performance. Some schemes are based on mathematical problems that already have security threats; It is caused by the theft of identity information, or it may be caused by the hijacking of equipment

Embodiment Construction

[0059] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0060] The present invention proposes an SM9-based vehicle networking V2I two-way authentication method, which applies the SM9 algorithm and PUF function to perform two-way identity authentication on vehicles and roadside units in a comprehensive VANET communication system.

[0061] VANET is a large-scale interactive network, a special mobile self-organizing network, which can realize the collection, integration and extraction of vehicle information, and use it to provide route planning, road condition monitoring, online tracking, emergency warning, multiple entertainment, etc. Comprehensive services have very important practical significance. The vulnerability of V2I wireless communication makes the network extremely vulnerable to security threats. To ensure network security, it is necessary to authenticate the two parties in wireless communication. ...

Abstract

The invention discloses an SM9-based V2I two-way authentication method for the Internet of Vehicles, which belongs to the field of wireless communication security and authentication protocols for the Internet of Vehicles. First, establish a VANET communication system including a trusted third party TA, server, roadside unit RSU and vehicle V, and initialize the parameters of the VANET communication system through the SM9 cryptographic algorithm, and then use the initialized parameters to generate the system key and identifier hid. Input the identity ID of the RSU into the built-in PUF module of the RSU, output the response stimulus Y, and pre-store the ID of the RSU and the stimulus-response pair (ID, Y) in the vehicle V. Using the identifier hid of the master private key, the ID of the RSU and (ID, Y), through three interactive communications, the two-way authentication of RSU and V is realized. After the two-way authentication is completed, the VANET communication system can carry out multi-vehicle communication in motion. The invention improves the communication security, reduces the number of interactions, improves the communication efficiency, and is well adapted to the rapid movement of multiple vehicles in the Internet of Vehicles environment.

Description

technical field [0001] The invention belongs to the field of wireless communication security and authentication protocols of the Internet of Vehicles, and specifically refers to an SM9-based V2I two-way authentication method for the Internet of Vehicles. Background technique [0002] Nowadays, the development of the automobile industry is no longer simply satisfied with the needs of travel, but more consideration is given to the user's driving experience, information services and entertainment enjoyment, especially the combination of vehicles and the rapidly developing network, which provides the best solution for realizing the needs of users. This opportunity has promoted the rapid development of VANET (Vehicular Ad-hoc NETwork, Vehicle Networking). [0003] VANET generally includes four entities: trusted third party TA (Trusted Authoriy, authentication center), server, RSU (Road Side Unit, roadside unit) and V (vehicle, vehicle). As a fixed static node, RSU is generally d...
