- Most modern electronic systems are hosted by printed circuit boards(PCBs), making them a ubiquitous system component that can take many different shapes and forms. In order to achieve a high level of economy of scale, the global supply chain of electronic systems has evolved into disparate segments for the design, fabrication, assembly, and testing of PCB boards and their various associated components.
- As a consequence, the modern PCB supply chain exposes many vulnerabilities along its different stages, allowing adversaries to introduce malicious alterations to facilitate board-level attacks. As an emerging hardware threat, the attack and defense techniques at the board level have not yet been systemically explored and thus require a thorough and comprehensive investigation.
- In the absence of a standard board-level attack benchmark, current re-search on perspective countermeasures is likely to be evaluated on proprietary variants of ad-hoc attacks, preventing credible and verifiable comparison among different techniques. Upon this request, we have created the PCBench, which is a set of board-level attack benchmarks for open-source release.
- A broad range of board-level attacks are defined and categorized.
- For the first time, the attack vectors and construction rules for board-level attacks were developed.
- A practical and reliable board-level attack benchmark generation scheme was also developed, which can be used to produce references for evaluating countermeasures.
- To facilitate the development of board-level attack benchmarks, representative circuit boards are chosen as the victim designs. Open-source hardware projects are mainly selected due to their modern design styles, the availability of PCB designs as well as detailed documents, firmware, and/or application software. As a result, researchers can easily reconstruct the board-level security evaluation benchmarks.
- The following table lists the released benchmarks:
|No. of Components
|No. of Layers
|Microcontroller devlopment board based on ATsam3x8e with ARM Cortex-M3 core
|Single-board Linux computer based on Allwinner-A13 with Cortex-A8 core
- Note that This is not the full list of benchmarks as we continue developing the new benchmarks.
- The fabricated Arduino-due board with and without Trojans are shown below.
- Input: PCB reference design and Board level attack vector
- Output: Board level Trojan inserted benchmark
