Abstract

This work proposes a framework for analyzing threats related to the semiconductor supply chain. The framework introduces a metric that quantifies the severity of different threats subjected to a collusion of adversaries from different stages of the supply chain. Two different case studies are provided to describe the real-life application of the framework. The metrics and analysis aim to guide security efforts and optimize the trade-offs of hardware security and costs.
