[0109] see Figure 4 As shown, the process of applying CA directly to the authorization server for an authorization token is as follows:

[0110] 0, the application CA establishes a trusted relationship with the authorization server, and the certificate application device establishes a trusted relationship with the authorization server. The trusted relationship can be based on a mechanism based on a symmetric key (shared key mechanism) or a mechanism based on an asymmetric key (such as the mechanism of PKI) to establish. In addition, this embodiment is described using an asymmetric key-based PKI mechanism, that is, both parties store the other party's public key certificate to verify the other party's digital signature.

[0117] see Figure 5 As shown, the process of the application CA indirectly obtaining the authorization token sent by the authorization server through the certificate application device is as follows:

[0118] 0, the application CA establishes a trusted relationship with the authorization server, and the certificate application device establishes a trusted relationship with the authorization server. The trusted relationship can be based on a mechanism based on a symmetric key (shared key mechanism) or a mechanism based on an asymmetric key (such as the mechanism of PKI) to establish. In addition, this embodiment is described using an asymmetric key-based PKI mechanism, that is, both parties store the other party's public key certificate to verify the other party's digital signature.

Abstract

The embodiment of the invention provides an application certificate application method and device, which are applied to an application certificate authority (CA). The method comprises the following steps: acquiring an authorization token sent by an authorization server; and sending a first application certificate response message to a certificate application device based on the authorization token, the first application certificate response message including an application certificate. According to the embodiment of the invention, the issuing process of the application certificate is realized in combination with a third-party authorization mechanism.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an application certificate application method and device. Background technique [0002] In the field of the Internet of Vehicles, the secure communication of the Internet of Vehicles is based on the public key infrastructure (Public Key Infrastructure, PKI), and the basic composition of the PKI of the Internet of Vehicles is also the same. [0003] Among them, the certificate application entity in the Internet of Vehicles system includes: On Board Unit (OBU) and Road Side Unit (Road Side Unit, RSU), where OBU is a communication device installed on the vehicle, responsible for the information of the vehicle to the outside world Exchange (vehicle to everything, V2X) message sending and receiving; RSU is installed on the communication device on the roadside device, responsible for sending and receiving the roadside device V2X message. [0004] In addition, the certif...
