The invention relates to an information security protection method and apparatus, and a computer-readable storage medium. The information security protection method comprises the steps of: allocating a train control and monitoring system to an intranet region, and performing region boundary security protection on the train control and monitoring system; performing communication network security protection on the train control and monitoring system; and performing terminal device security protection on the train control and monitoring system. The invention deeply integrates an application service of a train control and monitoring system, and defence-in-depth is performed on the train control and monitoring system from a plurality of dimensions such as region boundary security, communication network security and terminal device security, such that attacks initiated from an intranet and an extranet of the system can be effectively handled, and thus, the information security protection capability of the train control and monitoring system is improved.

Information security protection method and apparatus

A method and a system for rail transit communication. The method includes: selecting a second target FSO transceiver from the FSO transceivers that are currently located within a signal coverage of a target FSO base station, in response to detecting that a first target free-space-optics (FSO) transceiver moves out of the signal coverage of the target FSO base station when data communication between the target FSO base station and the target user terminal is performed via the first target FSO transceiver, where the target FSO base station is one of the FSO base stations located on the rail; and maintaining the data communication between the target FSO base station and the target user terminal, by using the second target FSO transceiver. Handover among the base stations is reduced for user equipment, data communication rate is increased, and communication experience of passengers can be improved.

Rail transit communication method and system

Disclosed is a method for wireless typology discovery for train backbone networks. The method comprises steps of: receiving a data from a neighboring backbone node (BN), by a BN in a train backbone network through one directional antenna of at least one pair of directional antennas provided thereon; recording a receiving direction of said data, and determining said data to be a hello frame or a typology frame; performing neighbor discovery or topology discovery based on the type of said data; in neighbor discovery phase, performing a pair consistency check with respect to all the data received by the BN from a same direction, so as to identify a neighboring BN of the BN, and at the same time, stopping receiving hello frames from said direction by the BN; in typology discovery phase, updating a local typology table of the current BN based on the received typology frames; and performing a topology convergence check to see if any change occurs to the local typology table of the current BN, and if no change occurs, reporting on the status of the typology discovery phase to an up-level application.
