A method for providing control accesses between a device on a non-proprietary bus and a device on a proprietary bus is disclosed. A gateway controller is connected between a proprietary bus and a non-proprietary bus. A message originated from a device on the non-proprietary bus intended for a device on the proprietary bus is checked by the gateway controller to determine if a transmission of the message should be permitted according to a permitted message bitmap. The permitted message bitmap contains a list of devices on the non-proprietary bus that are previously registered as able to communicate with devices on the proprietary bus and a list of permitted messages associated with each of the devices on the non-proprietary bus. The transmission of the message to the device on the proprietary bus is denied if the message is not registered within the permitted message bitmap.
A method for controlling communication between a device on a non-proprietary bus and a device on a proprietary bus, said method comprising the steps of:
A system capable of providing data communications between a proprietary bus and a non-proprietary bus, wherein each of said proprietary bus and said non-proprietary bus is connected to a plurality of devices, said system comprising:
A computer program product residing on a computer usable medium for providing data communications between a proprietary bus and a non-proprietary bus, wherein each of said proprietary bus and said non-proprietary bus is connected to a plurality of devices, said computer program product comprising:
