Abstract

The invention relates to a method and device for information security and confidentiality for a rail transit on-board signal control system. The method adds a domestic password protection technology to the on-board signal system part of a communication-based train control system, and the on-board signal system adds a domestic password protection technology. After that, the workflow of the security method includes a chip filling phase, a certificate revocation list update phase, an identity authentication and session key negotiation phase, and an application data communication phase. Compared with the prior art, the present invention applies the data encryption technology to the end-to-end application layer equipment of the vehicle-ground wireless communication of the signal system, thereby improving the information security level of the vehicle-ground wireless communication and the like.

Description

technical field [0001] The invention relates to a method and device for information security and confidentiality, in particular to a method and device for information security and security used in a rail transit vehicle-mounted signal control system. Background technique [0002] In the communication-based rail transit train control system, its on-board controller communicates with the trackside system through the train-ground wireless system, obtains information related to train operation control, performs train control calculations, and outputs train control commands. The physical medium of its transmission exists in the open space, and there is a certain risk of unauthorized access, and its security communication standard must meet the requirements specified in EN50159-2. At present, only the general standard encryption technology is used in the communication layer of the vehicle-ground wireless, but only the integrity check technology is used for the transmitted applicat...
