Body authority control method and device based on Internet of Vehicles, and storage medium

Abstract

The embodiment of the invention discloses a subject authority control method and device based on the Internet of Vehicles and a storage medium, and relates to the technical field of the Internet of Vehicles. The method comprises the steps that an opposite terminal CA certificate and a request message sent by an opposite terminal are acquired, the request message comprises a data type requested by the opposite terminal, and a data type field allowing the request is pre-written in the opposite terminal CA certificate; analyzing the data type field from the opposite-end CA certificate, and determining at least one target data type allowed to be requested; and determining the consistent data type in the target data type and the data type requested by the opposite terminal, and sending the data conforming to the consistent data type to the opposite terminal. According to the embodiment of the invention, the CA certificate is adopted to carry out authority control on the data type transmitted between the vehicle networking main bodies.

Description

technical field [0001] The embodiments of the present invention relate to the Internet of Vehicles technology, and in particular to a method, device and storage medium for subject authority control based on the Internet of Vehicles. Background technique [0002] The V2X CA certificate is a CA certificate used in the V2X communication of the Internet of Vehicles (the information interaction between the vehicle and everything). Different from the traditional Internet X.509 CA certificate, the V2X CA certificate is small in size and designed for V2X scenarios. CA certificate is a digital certificate issued by CA (Certification Authority), mainly including issuer, user, version, signature algorithm, signature hash algorithm, user and public key, etc. The identity authentication and data encryption between the device and the server) can ensure the communication security between the participating subjects of the Internet of Vehicles, and effectively guarantee the integrity and con...

Problems solved by technology

[0003] The traditional V2X CA certificate as a communication ID card will not interfere with the authenticity of the transmitted data. Even if the participating subject is attacked, based on the CA certificate, the transmitted data will still be trusted in a short period of time, and the attacked subject will leak or excessively capture sensitive data, causing Internet of Vehicles Security Risks
