Engineering Ecosystems of Systems: UML Profile, Credential Design, and Risk-balanced Cellular Access Control

This thesis proposes an Ecosystem perspective for the engineering of SoS and CPS
and illustrates the impact of this perspective in three areas of contribution category
First, from a conceptual and Systems Engineering perspective, a conceptual framework
including the Ecosystems of System Unified Language Modeling (EoS-UML) profile, a
set of Ecosystem Ensemble Diagrams, the Arms :Length Trust Model and the Cyber
Physical Threat Model are provided. Second, having established this conceptual view of
the ecosystem, we recognize unique role of the cryptographic credentials within it,
towards enabling the ecosystem long-term value proposition and acting as a value
transfer agent, implementing careful balance of properties meet stakeholder needs.
Third, we propose that the ecosystem computers can be used as a distributed compute
engine to run Collaborative Algorithms. To demonstrate, we define access control
scheme, risk-balanced Cellular Access Control (rbCAC). The rbCAC algorithm defines
access control within a cyber-physical environment in a manner which balances cost,
risk, and net utility in a multi-authority setting. rbCAC is demonstrated it in an Air Travel
and Border Services scenario. Other domains are also discussed included air traffic
control threat prevention from drone identity attacks in protected airspaces.
These contributions offer significant material for future development, ongoing credential
and ecosystem design, including dynamic perimeters and continuous-time sampling,
intelligent and self optimizing ecosystems, runtime collaborative platform design
contracts and constraints, and analysis of APT attacks to SCADA systems using
ecosystem approaches.
