A method for transmitting an automobile electronic identification, an on-board device, and a reader

Abstract

Embodiments of the present application provide a method for transmitting an electronic identification of an automobile, an on-vehicle device, and a reader / writer. In this method, the vehicle-mounted device receives a read request message from the reader, and the read request message is used to request to read the vehicle electronic identification stored in the vehicle-mounted device. After receiving the read request message, the vehicle-mounted device verifies the reader through the read request message, and encrypts the electronic identification of the vehicle after confirming that the verification is passed; then, the vehicle-mounted device sends a read response message to the reader-writer, and the read response message contains Contains the encrypted vehicle electronic identification. Through this scheme, the reader is verified by using the computing power of the vehicle-mounted equipment, which is superior to the existing electronic tags. After confirming that the reader has the right to read the vehicle electronic identification stored in the vehicle equipment, the vehicle electronic identification is encrypted and the response message is read. Sending to the reader, compared with the existing method, reduces the number of rounds of information interaction, saves costs, and improves the security of automotive electronic identification transmission.

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...

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.
