Problems solved by technology

It can be seen that before the reader reads the vehicle information stored in the electronic tag, it needs to go through multiple rounds of interaction to establish a safe channel. The number of interactive messages is too large and the cost is relatively high.

example 1

[0143] Example 1: Reference image 3 As shown, the automobile electronic identification transmission method provided in this example includes the following steps:

[0144] S301: The reader / writer sends a read request message to the vehicle-mounted device through the PC5 interface, and the read request message includes the identifier of the reader / writer.

[0145] Wherein, the read request message is a message signed by the reader-writer using the application certificate of the reader-writer.

[0146] S302: The vehicle-mounted device determines that the legal reader-writer identification set stored locally includes the reader-writer identification, determines that the application certificate corresponding to the signature of the read request message is legal, and determines that the signature of the read-request message is correct.

[0147] The specific process can refer to figure 2 The specific description in S202 in the illustrated embodiment will not be repeated here.

Abstract

The embodiment of the invention provides an automobile electronic identifier transmission method, vehicle-mounted equipment and a reader-writer. In the method, the vehicle-mounted equipment receives a read request message from the reader-writer, and the read request message is used for requesting to read an automobile electronic identifier stored in the vehicle-mounted equipment. After the vehicle-mounted equipment receives the read request message, the reader-writer is verified through the read request message, and after it is determined that verification is passed, the vehicle electronic identifier is encrypted; and then, the vehicle-mounted equipment sends a read response message to the reader-writer, and the read response message comprises the encrypted automobile electronic identifier. According to the scheme, the reader-writer is verified by utilizing the computing power of the vehicle-mounted equipment superior to that of the existing electronic tag, and after it is determined that the reader-writer has permission to read the automobile electronic identifier stored in the vehicle-mounted equipment, the automobile electronic identifier is encrypted and sent to the reader-writer through the read response message, so that compared with the existing mode, the information interaction turns are reduced, and the overhead is saved; and meanwhile, the transmission safety of the automobile electronic identifier is improved.

Description

technical field [0001] The present application relates to the technical field of the Internet of Vehicles, in particular to a method for transmitting an electronic identification of an automobile, an on-vehicle device, and a reader. Background technique [0002] The electronic registration identification of the motor vehicle (ERI) is an extension of the Internet of Things passive radio frequency identification (Radio Frequency Identification, RFID) in the field of smart transportation. ERI can specifically be the vehicle information such as the license plate number stored in the electronic tag. Among them, the electronic tag is a chip that can be attached to the vehicle. The electronic tag can also be called the electronic ID card of the car, the digital standard information source of the car, commonly known as the "electronic license plate". The reader placed in other traffic infrastructure interacts with the electronic tag to obtain the electronic identification of the veh...
