Interoperability challenge of certified communication systems via internet

Developing the full potential of Information and Communication Technology (ICT) can greatly innovate and promote society in a number of sectors, including eCommerce, eGovernment, and eHealth. The European Commission works to innovate and bring ICT to its full potential in any sector. Lack of interoperability and adherence to international standards heavily impacts on economic growth and competitiveness. This study suggests a conceptual model to support and fuel worldwide interoperability of Internet Certified Communication Systems (CCSs) worldwide. Current European CCS systems certify the source of an email or message but they also address specific national needs (government) by implementing closed solutions, which impedes cross-border and worldwide interoperability. The Generic CCS model (GCCS) defines an open solution that is able to redefine "closed" CCS systems, planting the seed for building worldwide interoperability between certified communication systems. Few scenarios of use illustrate the potential of the proposed model.
