The University of South Australia is investigating the highly complex integration of information systems within the CRC for integrated engineering asset management (CIEAM) and develops techniques and tools to simplify the data exchange between enterprise critical systems. Recent research outcomes include a service oriented integration architecture, an integration toolbox and a service interface for the integration of asset management information systems. In this paper we also propose an extension on the architecture level for enabling a secure data exchange between multiple systems. It allows the secure information sharing internally within an enterprise but also externally with business partners and supports the current trend towards an open service oriented environment by protecting critical asset management data on a shared communication infrastructure.
