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.

Secure vehicle to vehicle PTC communication

A system that includes a lead locomotive in communication with one or more remote vehicles, and the lead locomotive including one or more processors configured to execute program instructions to perform functions based on the program instructions. These functions include determining a first characteristic related to the lead locomotive or the one or more remote locomotives, receiving historical data related to the first characteristic, comparing the first characteristic to the historical data to determine a change in first characteristic value, and determining a second characteristic related to the lead locomotive or the one or more remote locomotives. In response to the change in first characteristic value exceeding a threshold percentage, the one or more processors ignore the change in first characteristic value exceeding the threshold percentage based on the second characteristic.
