Embodiment 1

[0080] image 3 A schematic flowchart of the first authentication method provided by the embodiment of the present application is shown. The authentication method is applied to roadside units, and the details are as follows:

[0081] In S301, broadcast beacon service table (Beacon Service Table, BST) information.

[0082] In the embodiment of the present application, the roadside unit located on the road stores the BST information in advance, and the roadside unit may broadcast the BST information to the surrounding devices in real time or at regular intervals.

[0083] In S302, the vehicle service table (Vehicle ServiceTable, VST) information returned by the vehicle-mounted unit according to the BST information is received, and a communication connection is established with the vehicle-mounted unit according to the VST information.

[0084] After receiving the BST information, the vehicle-mounted unit passing by the roadside unit acquires the VST information pre-stored in th...

Embodiment 2

[0133] Figure 4 A schematic flowchart of the second authentication method provided by the embodiment of the present application is shown. The authentication method is applied to the vehicle-mounted unit, and the details are as follows:

[0134] In S401, the BST information broadcast by the roadside unit is received.

[0135] This step corresponds to step S301 in the previous embodiment, and the vehicle-mounted unit may receive the BST information broadcast by the roadside unit.

[0136] In S402, VST information is returned to the roadside unit according to the BST information, so as to establish a communication connection with the roadside unit.

[0137] After receiving the BST information, according to the BST information, send the VST information pre-stored by the on-board unit to the roadside unit, so that the roadside unit can establish a unicast link with the on-board unit according to the VST information to realize the communication connection between the two.

[0200] Image 6 A schematic structural diagram of a first authentication device provided by an embodiment of the present application is shown, where the first authentication device is applied to a roadside unit. For the convenience of description, only the parts related to the embodiments of the present application are shown:

[0201] The first authentication device includes: a broadcasting unit 61, a first connection unit 62, a target request instruction sending unit 63, a target ciphertext receiving unit 64, a decryption unit 65, a first authentication unit 66 and a target random number decryption result sending unit 67 . in:

[0202] The broadcasting unit 61 is used for broadcasting BST information.

[0203] The first connection unit 62 is configured to receive the VST information returned by the vehicle-mounted unit according to the BST information, and establish a communication connection with the vehicle-mounted unit according to the VST information.

Abstract

The invention is suitable for the technical field of vehicles, and provides an authentication method and device, electronic equipment and a storage medium, and the method comprises the steps that a road side unit sends a target request instruction to a vehicle-mounted unit, and the target request instruction carries a first random number of the road side unit; receiving a target ciphertext returned by the vehicle-mounted unit according to the target request instruction; the target ciphertext comprises a ciphertext of the target random number; the target random number is obtained according to the first random number and a second random number of the vehicle-mounted unit; performing decryption processing on the target ciphertext to obtain a target random number decryption result corresponding to the target random number; determining a first authentication result of the road side unit for the vehicle-mounted unit according to the decryption result of the first random number and the target random number; and sending the target random number decryption result to the vehicle-mounted unit to instruct the vehicle-mounted unit to determine a second authentication result of the vehicle-mounted unit for the road side unit according to the target random number decryption result and the second random number. According to the embodiment of the invention, mutual authentication of the road side unit and the vehicle-mounted unit can be efficiently realized.

Description

technical field [0001] The present application belongs to the technical field of vehicles, and in particular, relates to an authentication method, device, electronic device and storage medium. Background technique [0002] Electronic toll collection system (Electronic Toll Collection, ETC) is an intelligent transportation system that can realize automatic toll collection of vehicles. ETC usually includes a roadside unit (RSU) located on the road and an on-board unit (OBU) located on the vehicle. Through wireless data communication between the roadside unit and the on-board unit, the vehicle can automatically The interaction of inductive identification and related charging data makes it possible to automatically and efficiently implement vehicle charging without parking or setting a charging window. [0003] When implementing the ETC service, the roadside unit and the on-board unit need to perform mutual authentication with each other to ensure the safety and accuracy of veh...
