摘要： A computer-implemented method is provided that includes obtaining a first secret and a first public key, and obtaining a second secret a second public key. The method may also include authenticating the first public key of the first vehicle based on a first private key associated with the first vehicle, and authenticating the second public key of the second vehicle based on a second private key associated with the second vehicle. The method may also include preventing a man-in-the-middle attack, by securing at least one of a first vehicle-to-central office communication, a central office-to-first vehicle communication, or a first vehicle-to-second vehicle, wherein the first vehicle-to-central office communication and the central office-to-first vehicle communication are authenticated based on a determined private key associated with a respective first vehicle on-board computer, and sending a message, with the central office server, to a vehicle associated with a conditional movement authority.

摘要： A method of communication monitoring. The method may include receiving wireless communication signal strengths measured in different areas from one or more communication devices disposed onboard a first system moving through the different areas or stationary communication devices at wayside locations in the different areas. The method may include receiving locations where the wireless communication signal strengths were measured. The method may then include determining a spatial distribution of the wireless communication signal strengths based on values of the wireless communication signal strengths that were measured and the locations where the wireless communication signal strengths were measured. The method may include changing operation of a second system based on the spatial distribution that may be determined.

摘要： A method is provided that can include activating at least two wireless communication channels in parallel, between a first wireless transceiver and a second wireless transceiver. Each of the at least two wireless communication channels can operate at a different radio carrier frequency, and the first wireless transceiver may be part of a first vehicle. The method can also include transmitting, by the first wireless transceiver, common information in parallel on the at least two wireless communication channels to the second wireless transceiver and deactivating the at least two wireless communication channels.
