Distributed Federated Collaboration Secured Services is a proposed novel secure distributed Unified Communication and Collaboration (UCC) reference architecture planned for multi-environment ecosystems (including hybrid cloud, edge computing for IoT and real-time usages, and portable scenarios). DFCS-RA encourages new businesses and models, connecting people, “things,” and processes in secured and sensitive workloads, supporting efficient and cost-effective enhancements to traditional UCC (mostly centralized/monolithic services) tailored for different vertical markets having varying requirements. It provides a novel secure multi-environment communication and collaboration technology and services between large numbers of players. Key security concepts developed are secure separation, federation, and collaboration. The cryptographic architecture extends the Signal messenger security and encryption architecture. DFCS-RA comprises a toolbox for security modeling, a set of security design principles, and a set of security functions and mechanisms to implement controls to achieve stated security objectives. It was tested in diverse use cases; and found suitable, secure, and reliable.
