Embodiment Construction

[0028] Such as figure 1 As shown, the privacy protection authentication system based on digital re-signature and traceability technology described in the present invention is composed of authentication center system 3 system 3, roadside unit RSU2 (Road-Side Units) and vehicle-mounted unit OBU1 (On board Unit) ; The authentication center system 3, the roadside unit RSU2 and the vehicle-mounted unit OBU1 communicate with each other through a wireless network.

[0029] The authentication center system 3 is composed of a group of traffic management bureau servers, the roadside unit is placed beside the road on which the vehicle travels, and the vehicle-mounted unit OBU is arranged on the motor vehicle.

[0030] The certification center system 3 initializes the system, establishes system security parameters, and the certification center system 3 generates a public-private key pair, and then uses the key to generate a public-private key pair for the roadside unit RSU2, and distribut...

Abstract

A privacy protection and authentication system based on digital re-signature and traceability technology is composed of an authentication center system, a road-side units (RSU) and on-board units (OBUs). The authentication center system, the RSU and the OBU are in interconnection with each other through a wireless network, the authentication center system generates a corresponding re-signature secret key for each OBU according to identification parameters of the OBUs, and the re-signature secret keys are used for performing re-signature on information. Simultaneously, a public key of the authentication center system, the RSU and the OBUs is used for tracing back to information senders. The privacy protection and authentication system based on the digital re-signature and traceability technology has the advantage that safety of the vehicle ad-hoc network privacy protection and authentication system based on the agent re-signature technology combines information authentication and privacy protection, is small in actual communication protocol interaction times and low in vehicle unit storage cost and consultative communication cost, and has certain performance advantages and practical potential.

Description

technical field [0001] The invention relates to the field of privacy protection of the Internet of Vehicles, in particular to a privacy protection authentication system for an ad hoc network of vehicles based on digital re-signature technology. Background technique [0002] With the large-scale and high-frequency use of vehicles in modern society, through the establishment of vehicular ad hoc networks (VANETs), also known as the Internet of Vehicles, the Internet of Vehicles constitutes the basic environment of the "smart car" network. On the one hand, the Internet of Vehicles can effectively improve the driving experience. Drivers can effectively understand the real-time driving environment and accurately locate the location of surrounding friends through location sharing services; on the other hand, it can effectively relieve traffic pressure and reduce traffic accidents. However, there is a possibility that user privacy information may be leaked in the Internet of Vehicle...
