Embodiment 1

[0071] Such as figure 1 As shown, this embodiment is used for the intelligent identity authentication method of rail transit equipment, and the steps include:

[0072] 1) Pre-load an identity authentication module in the required device;

[0073] 2) When the devices on both sides of the communication need to communicate or perform data exchange, start the identity authentication module in the device, the identity authentication module will establish a connection between the two devices of the communication, and encrypt the local identity mark with the public key of the other party and sign it with the local private key Send it to the other party's device, and compare it with the locally stored identity mark after obtaining the identity mark of the other party's device to verify the legal identity of the other party's device.

[0074] In this embodiment, the specific steps of step 2) are: when the source device and the target device need to communicate or perform data exchange...

Embodiment 2

[0116] The difference between this embodiment and Embodiment 1 is that when it is the first identity authentication, the step 2) also includes the intelligent initialization step of the legal identity of the device, such as Figure 5 As shown, the specific steps are:

[0117] S1) Load an initialization module in the required device in advance;

[0118] S2) When the source device communicates with the target device or performs data exchange, if it is the first identity authentication, the initialization module in the source device will be started, and the initialization module will establish a connection between the source device and the target device, and judge whether the local of the source device is connected each time a connection is established. There is a legal identity mark corresponding to the target device, and if it is judged that there is no legal identity mark, the corresponding legal identity mark is obtained from the target device.

[0119] In this embodiment, w...

Abstract

The invention discloses a smart identity authentication method and device for a rail transit device. The method comprises the steps of 1), preloading an identity authentication module in a required device; and 2), when two communication party devices need to communicate or perform data exchange, the identity authentication module in the device is started, the connection between the two communication party devices is established by the identity authentication module, a local identity mark is encrypted through a public key of an opposite party and is signed by a local private key and then is sent to an opposite device, and after the identity mark of the opposite device is obtained, the identity mark is compared with a locally stored identity mark, thereby authenticating the legal identity of the opposite device. The method and the device are applicable to the rail transit device for realizing smart identity authentication, and the method and the device have the advantages that the realization method is simple, the required cost is low, the identity authentication efficiency is high and the method and the device are safe and reliable.

Description

technical field [0001] The invention relates to rail transit communication, in particular to an intelligent identity authentication method and device for rail transit equipment. Background technique [0002] At present, in the communication and data transmission process of rail transit equipment, the target device of communication is usually regarded as a legal device by default, and then the legitimacy of both communication parties is ensured based on management methods such as identity signs and smart cards. Valid methods for authentication. However, to determine whether the target device is legal through management means, it is very easy to verify that the illegal device is a legal device due to management omissions or mistakes, and there are very large security risks in the device communication and data transmission process. For example, in the train-to-ground wireless transmission system, it is necessary to transmit the data of each terminal of the train to the on-boar...
