Abstract:
A railway safety critical application system substitutes commercial off-the-shelf (COTS) hardware and/or software for railway-domain specific product components yet is validated to conform to railway safety critical system failure-free standards. The safety critical system uses a pair of tasks executed on a controller of a COTS personal computer or within a virtual environment with asymmetric communications capability. Both tasks receive and verify safety critical systems input message data and security code integrity and separately generate output data responsive to the input message. The first task has sole capability to send complete safety critical system output messages, but only the second task has the capability of generating the output security code. A failure of any of systems hardware, software or processing capability results failure to transmit a safety critical system output message or an output message that cannot be verified by other safety critical systems.

Claim (Index 10):
A railway system comprising:\n a plurality of control systems for controlling railway safety critical systems, the control systems communicatively coupled to each other for receipt and transmission of safety critical systems messages respectively having safety critical data and a security code, the respective control systems comprising:\n at least one controller executing first and second software instruction sets; \n the first software instruction set capable of sending and receiving a safety critical systems message that is generated within the railway system; \n the second software instruction set capable of receiving a safety critical systems message, but incapable of sending a safety critical systems message that is generated within the second software instruction set, the second software instruction set having a security code generator; \n and a communications pathway coupling the first and second software instruction sets; \n wherein the first and second software instruction sets respectively receive an input safety critical systems message including input safety critical systems data and an input security code, verify the input message integrity and generate output safety critical systems data, the second software instruction set generates an output security code and sends it to the first software instruction set, and the first software instruction set sends an output safety critical systems message including the output safety critical systems data and the second software instruction set output security code, for use within the railway system.
