Authentication method, electronic equipment and storage medium

Abstract

The invention discloses an authentication method, electronic equipment and a storage medium. The authentication method is applied to a road side unit, and comprises the following steps: obtaining target identity recognition information, the target identity recognition information being identity recognition information of a target on-board unit; according to the target identity identification information and stored authentication information, determining a first authentication result of the road side unit to the target on-board unit; under the condition that the first authentication result indicates that the authentication is valid, acquiring a second authentication result of the target vehicle-mounted unit on the road side unit; under the condition that the first authentication result or the second authentication result indicates that the authentication is invalid, performing bidirectional authentication operation with the target on-board unit; and sending the target authentication information to other downstream road side units. According to the scheme of the invention, the bidirectional authentication efficiency of the vehicle-mounted unit and the multi-side unit can be improved, and the authentication convenience and the communication security can be considered when the security authentication technology is applied in the ETC system.

Description

technical field [0001] The present application belongs to the technical field of the Internet of Things, and in particular, relates to an authentication method, an electronic device and a computer-readable storage medium. Background technique [0002] At present, the security authentication technology of the point-of-sale terminal security access module (Purchase Secure Access Module, PSAM)-Embedded Secure Access Module (ESAM) is relatively mature. In an existing electronic toll collection (Electronic Toll Collection, ETC) system, a road side unit (Road Side Unit, RSU) includes a PSAM, and an onboard unit (On Board Unit, OBU) includes an ESAM. On this basis, the one-way authentication technology of the roadside unit to the vehicle unit has been widely used. [0003] However, compared with the two-way authentication technology, the one-way authentication technology cannot well guarantee the communication security between the roadside unit and the vehicle-mounted unit, which ...

Problems solved by technology

[0003] However, compared with the two-way authentication technology, the one-way authentication technology cannot well guarantee the communication security between the roadside unit and the vehicle-mounted unit, which makes people start to consider applying the two-way authentication technology in the ETC system

Due to the large number of roadside units in the ETC system, one vehicle-mounted unit often needs to perform data interaction with different roadside units successively, which makes the authentication process too complicated

That is to say, the existing security authentication technology is difficult to balance authentication convenience and communication security in the ETC system
