V2X anonymous certificate management method and device in Internet of Vehicles, storage medium and equipment

Abstract

The invention discloses a V2X anonymous certificate management method and device in the Internet of Vehicles, a storage medium and equipment, and the management method comprises the steps: receiving an anonymous certificate request which is transmitted by vehicle-mounted terminal equipment and comprises a registration certificate, an anonymous certificate batch number and a certificate index value of the vehicle-mounted terminal equipment through an authorization mechanism; decrypting and verifying the request, and searching a corresponding anonymous certificate application record after verification is passed; if the application records of the same batch number of the same certificate exist, judging whether the request is sent repeatedly or not according to the certificate index value; if yes, reporting an error; and otherwise, carrying out assignment processing on the valid period of the requested batch anonymous certificate. Therefore, the method does not depend on the capability of providing a trusted clock by terminal equipment, and the equipment cost is reduced; Meanwhile, based on the mode that the PKI system carries out validity period distribution on the pre-applied anonymous certificates, the possibility that a large number of anonymous certificates are maliciously applied after the equipment is intruded can be prevented, and the information security protection capability of the system is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of network security, and in particular to a method for managing a V2X anonymous certificate in the Internet of Vehicles, a computer-readable storage medium, a computer device, and a management device for a 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, which 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 enhance the vehicle's perception of surrounding conditions, while further improving traffic safety, traffic efficiency and human-vehicle interaction. Vehicles based on V2X technology can exchange information su...

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.
