Management method and device, storage medium and device for v2x anonymous certificate in the Internet of Vehicles

Abstract

The invention discloses a management method and device, a storage medium and equipment for a V2X anonymous certificate in the Internet of Vehicles. The management method includes: receiving a registration certificate and an anonymous certificate batch including the vehicle terminal equipment and sent by the vehicle terminal equipment through an authorized institution. An anonymous certificate request with a certificate number and a certificate index value; decrypt and verify the request, and find the corresponding anonymous certificate application record after the verification is passed; if there is an application record with the same certificate and the same batch number, the request is judged according to the certificate index value Whether it is repeated sending; if yes, an error will be reported; otherwise, the validity period of the requested batch anonymous certificate will be assigned. Therefore, the method does not need to rely on the ability of the terminal device to provide a trusted clock, thereby reducing the cost of the device; at the same time, based on the way in which the PKI system assigns the validity period of the pre-applied anonymous certificate, it can prevent the possibility of maliciously applying for a large number of anonymous certificates after the device is invaded , effectively improve the information security protection capability of the system.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a management method of a V2X anonymous certificate in the Internet of Vehicles, a computer-readable storage medium, a computer device and a management device of the V2X anonymous certificate in the Internet of Vehicles. Background technique [0002] The development of IoT applications in the automotive industry has promoted vehicle-based interconnection applications. These applications mainly include vehicle-to-vehicle V2V (Vehicle to Vehicle), vehicle-to-roadside equipment V2I (Vehicle to Infrastructure), and vehicle-to-pedestrian broadcast-based communication Technology, generally referred to as V2X (Vehicle to Everything). The main purpose of V2X technology is to improve the vehicle's ability to perceive the surrounding state, while further improving traffic safety, traffic efficiency and human-vehicle interaction. Vehicles based on V2X technology can exchange informa...

Problems solved by technology

In related technologies, the application for anonymous certificates is generated and actively uploaded by the on-board device, and the private key of the certificate is completely processed by the device to ensure the security of the certificate key. For certificates with the same validity period, although the authority does not know the specific vehicle information, there is still a risk of privacy leakage because multiple anonymous certificates can be associated with the same vehicle; if for privacy considerations, each anonymous certificate application only Corresponding to an anonymous certificate, the PKI (Public Key Infrastructure) system under the existing mechanism can only judge whether different anonymous certificate applications correspond to the same validity period based on the expected validity period information of the device. Considering that the device may not have the There is a certain security risk in determining the validity period of the certificate based on the time information provided by the device.
