Example Embodiment

[0083]In order to have a clearer understanding of the technical features, objectives and effects of the embodiments of the present invention, specific implementations of the embodiments of the present invention will now be described with reference to the drawings.figure 1 A schematic diagram of a typical example of a rail transit control system. As shown in the figure, there are exemplarily two rail vehicles 104 running on the rail line 103. An on-board control device 101 is installed on the rail vehicle 104. The area control device 102 is installed corresponding to the track line 103, for example, installed near a specific station on the track line 103. It should be understood that the area control device 102 may be set corresponding to each station of the track line 103, or may be set for some stations, which is not limited in this embodiment.

[0084]Specifically, wired or wireless communication may be performed between different area control devices 102, and different rail vehicles...

Abstract

The embodiment of the invention relates to a communication method and device in rail transit and a storage medium. The communication method is applied to a control system of rail transit, the system comprises a first control device and a second control device, and the method comprises the following steps: the first control device performs digital signature processing based on transmission information of rail transit by using a first private key to obtain a security authentication message; the first control device sends the security authentication message to the second control device; and the second control device uses a first public key to perform identity authentication based on the safety authentication message, and the first public key and the first private key form an asymmetric key. According to the scheme of the embodiment of the invention, the safety of communication between the control devices is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of rail transit, and in particular to a communication method, device and storage medium for secure communication in rail transit. Background technique [0002] In the communication-based train control system (Communication based Train Control, CBTC) rail transit signaling system, the communication between trains and ground, between regional control equipment and between vehicles is related to the operating efficiency of the entire system. Generally, the stability of communication based on wired connection is high, but it will be limited by geographical conditions. The wireless communication connection method greatly reduces the limitation of geographical conditions. The above communication methods have been proposed, but the communication security problem has become a new issue. challenge. [0003] However, there is room for improvement in communication security between control devices such ...
