Abstract

The invention discloses a method and device for securely transmitting ETC broadcast messages, and the method comprises the steps: configuring a public and private key pair for each section of a highway in advance; when it is detected that the vehicle-mounted unit arrives at the entrance of the road section, establishing a safety link with the vehicle-mounted unit based on a preset safety mechanism; sending a public key corresponding to the current section road section to the vehicle-mounted unit based on the safety link; and encrypting a to-be-sent broadcast message by using the private key corresponding to the current section road section, and sending the encrypted broadcast message to the vehicle-mounted unit. By adoption of the ETC broadcast message secure transmission method provided by the invention, the security authentication of the ETC broadcast message can be achieved, the situation that the fake road side unit broadcasts the fake message is effectively avoided, and the security of the ETC broadcast message is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of intelligent transportation, in particular to a method and device for secure transmission of ETC broadcast messages, and also to an electronic device and a computer-readable storage medium. Background technique [0002] In recent years, with the acceleration of infrastructure construction, more and more expressways have been equipped with corresponding ETC (Electronic Toll Collection) systems. Through the dedicated short-range communication between the on-board unit (On Board Unit, OBU) installed on the vehicle windshield and the road side unit (Road Side Unit, RSU) on the ETC lane of the toll station, it uses computer networking technology to communicate with the bank. Background settlement processing, so as to achieve the purpose of paying the expressway or bridge toll without stopping the vehicle through the expressway or bridge toll station. In addition to being used for settleme...
