摘要：
Positive Train Control (PTC) is a wireless control system ensuring railroad safety by enforcing train separation, speed enforcement, roadway worker protection and other safety functions. Due to shared trackage rights over each-other's tracks in North America, company A's trains must be safely operated by company B's crew on company C's tracks, requiring different PTC systems to securely interoperate with each other. We propose using a trust management system with certificates and over the air re-keying (OTAR) as a security framework to ensure secure interoperation. Preliminary estimates show that our solution meets timing needs of PTC.
