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 and a method may include one or more sensors disposed onboard a vehicle that may sense one or more characteristics of the vehicle. The system may include one or more processors configured to determining an identification of a switch on a route along which a vehicle moves using one or more sensors onboard the vehicle. A location of the switch is identified with the one or more sensors. A state of the switch is determined with the one or more sensors. The identification of the switch, location of the switch, and the state of the switch are communicated with an off-board database.
