Abstract: Protection and integration of proprietary data in an open system architecture, which includes at least one sub-system, and which must comply with an open standard interface mandated by the system owner. The open standard interface defines the set of messages or signals which may be exchanged by sub-system components. The sub-system provider computer is granted a bridge node to instantiate within their controlled sub-system boundary. The bridge node communicates with the sub-system components via the interchangeable open standard interface and relays messages or signals to other sub-system bridge nodes through a shared common bus. The sub-system provider may protect their proprietary data in their standard interface implementation from the system owner and/or other sub-system providers in the overall system. This is achieved by removing the need for sub-system providers to share their open standard interface implementations with each other in order to integrate together into the overall system.
