The globalized supply chain allows microelectronics to pass through numerous untrusted entities before reaching their final destination. This creates unknown risks of counterfeit integrated circuits IC being installed into mission critical systems. Methods of detecting counterfeits ICs are plentiful however, methods to quantify the risks of counterfeits in the supply chain are not well researched. In this work, we propose a unique methodology for modeling risk in the electronics supply chain. We enable each entity to calculate their relative risks through quantitative, data-driven confidence levels. We use intrinsic, internal, and external hardware properties to quantify the risk of counterfeit ICs at each stage of the supply chain. Leveraging a secure, cloud-based distributed ledger tailored for the electronics industry, we enable authentication of components throughout the supply chain. We provide case studies demonstrating how an untrusted entity can use our model to calculate the confidence level of authentication and relative risks from counterfeit ICs. Our approach provides important first steps toward holistic risk assessments of the globalized electronics supply chain.
