Abstract :
Positive train control (PTC) is an electronic system that enforces activities such as train separation, speed enforcement, and roadway worker protection essential to operate railroads safely and efficiently. Vehicular ad-hoc networks (VANETS) provide distributed real time communication of traffic hazards and road conditions among vehicles in a radio line of sight. Communicating PTC VANET systems offer the potential to reduce highway rail intersection (HRI) collisions by communicating train movement information to highway vehicles. For this to occur, different PTC systems must securely interoperate with each other. This outlines a PTC security framework utilizing using a certificate based trust management system and over the air re-keying (OTAR) to support interoperation.
