The embodiment of the invention discloses a digital certificate issuing and updating method, a CA system and a storage medium, and relates to the technical field of vehicle safety. The digital certificate issuing method comprises the following steps: storing filing information provided by a filing party; receiving a digital certificate signing and issuing request message sent by the Internet of Vehicles device, wherein the signing and issuing request message comprises a first identification code corresponding to a vehicle requesting to sign and issue a certificate; an analysis request message is sent to a third-party identification analysis system, and the analysis request message comprises the first identification code, so that the third-party identification analysis system analyzes the first identification code to obtain corresponding vehicle information; if the analyzed vehicle information obtained from the third-party identification analysis system is inconsistent with the vehicle information including the first identification code in the record information, the signing and issuing are failed. According to the embodiment of the invention, a third-party identification analysis system is introduced to analyze the identification code of the vehicle, so that the degree of dependence on filing information is reduced.
Description
technical field [0001] The embodiment of the present invention relates to the technical field of vehicle safety, in particular to a method for issuing and updating a digital certificate, a CA system and a storage medium. Background technique [0002] The Internet of Vehicles is the realization of data interaction and information sharing among functional entities such as people, vehicles, roads, and platforms through information and communication technologies. The high frequency of communication between the vehicle and other entities increases the possibility of the vehicle being attacked. In order to solve the problem of communication security, digital certificates are used as vehicle identification information to resist security attacks such as information forgery and tampering. [0003] In the prior art, when a CA (Certificate Authoriy, authorized certification) system issues a digital certificate, it only relies on the filing information provided by the manufacturer for ...
