Trojan Insertion versus Layout Defenses for Modern ICs: Red-versus-Blue Teaming in a Competitive Community Effort
, New York University Abu DhabiAbstract
Hardware Trojans (HTs) are a longstanding threat to secure computation. Among different threat models, it is the fabrication-time insertion of additional malicious logic directly into the layout of integrated circuits (ICs) that constitutes the most versatile, yet challenging scenario, for both attackers and defenders. Here, we present a large-scale, first-of-its-kind community effort through red-versus-blue teaming that thoroughly explores this threat. Four independently competing blue teams of 23 IC designers in total had to analyze and fix vulnerabilities of representative IC layouts, whereas a red team of 3 experts in hardware security and IC design continuously pushed the boundaries of these defense efforts through different HTs and novel insertion techniques. Importantly, we find that, despite the blue teams’ commendable efforts, even highly-optimized layouts retained at least some exploitable vulnerabilities. Our effort follows a real-world setting for a modern 7nm technology node and industry-grade tooling for IC design, all embedded into a fully-automated and extensible benchmarking framework. To ensure the relevance of this work, strict rules that adhere to real-world requirements for IC design and manufacturing were postulated by the organizers. For example, not a single violation for timing and design-rule checks were allowed for defense techniques. Besides, in an advancement over prior art, neither red nor blue teams were allowed to use any so-called fillers and spares for trivial attack or defense approaches. Finally, we release all methods and artifacts: the representative IC layouts and HTs, the devised attack and defense techniques, the evaluation metrics and setup, the technology setup and commercial-grade reference flow for IC design, the encompassing benchmarking framework, and all best results. This full release enables the community to continue exploring this important challenge for hardware security, in particular to focus on the urgent need for further advancements in defense strategies.
