2025 Multi-Partner Project: Reverse Engineering Methods for Trusted Chip Design (RESEC)
abstract
The RESEC (REconstruction of highly integrated SECurity devices) project addresses the growing concerns of malicious modification and IP piracy in globally distributed supply chains. The project's primary objective is to develop, verify, and optimise a complete reverse engineering process for integrated circuits manufactured in technology nodes of 40 nm and below. This paper highlights the significant contributions of RESEC in the areas of sample preparation, computer vision, and netlist analysis, thereby extending the state-of-the-art in hardware reverse engineering. The project results are expected to profoundly impact the development and physical verification of trusted chips, paving the way for future research.

2023 VE-FIDES: Designing Trustworthy Supply Chains Using Innovative Fingerprinting Implementations
abstract
The project VE-FIDES will contribute with a solution based on an innovative multi-level fingerprinting approach to secure electronics supply chains against the threats of malicious modification, piracy, and counterfeiting. Hardware-fingerprints are derived from minuscule, unavoidable process variations using the technology of Physical Unclonable Functions (PUFs). The derived fingerprints are processed to a system fingerprint enabling unique identification, not only of single components but also on PCB level. With the proposed concept, we show how the system fingerprint can enhance the trustworthiness of the overall system. For this purpose, the complete system including tiny sensors, a Secure Element and its interface to the application is considered in VE-FIDES. New insights into methodologies to derive component and system fingerprints are gained. These techniques for the verification of system integrity are complemented by methods for preventing reverse engineering. Two application scenarios are in the focus of VE-FIDES: Industrial control systems and an automotive use case are considered, giving insights to a wide spectrum of requirements for products built from components provided by international supply chains.

2023 Counterfeit Detection by Semiconductor Process Technology Inspection
abstract
With world-wide distributed semiconductor supply chains and a scarcity of microelectronic products, counterfeit devices are gaining momentum. Sourcing products from trusted providers are the theoretical remedy, yet practice shows the reality. Forged electronics are entering the supply chain at a high rate and pose a threat to safety, reliability, and security. Academia and industry have established various pre- or post-production measures to effectively address this issue partially. Yet, several inadequately covered aspects of the field require improvements. First, this work introduces a rating scheme to enable the effective comparison between anti-counterfeiting methods. Recently published methods are compared using this scheme. Second, a novel, generic, generally applicable prover-verifier attestation framework for post-production anti-counterfeiting methods is established. Third, the work implements a new anti-counterfeit method. By introducing technological individual features, the method incorporates technology intrinsic features of the front-end semiconductor manufacturing process as technology distinctive characteristic. Profile parameters are extracted through pattern recognition and statistical methods which are compared to the expected technologies through distance metrics, allowing an assertion of device authenticity. Finally, the versatility of the method is experimentally validated through real samples. Overall, an accuracy of 100% is reported for seven samples which are checked for authenticity.

2022 Physical and Functional Reverse Engineering Challenges for Advanced Semiconductor Solutions
abstract
Motivated by the threats of malicious modification and piracy arising from worldwide distributed supply chains, the goal of RESEC is the creation, verification, and optimization of a complete reverse engineering process for integrated circuits manufactured in technology nodes of 40nm and below. Building upon the presentation of individual reverse engineering process stages, this paper connects analysis efforts and yields with their impact on hardware security, demonstrated on a design with implemented experimental hardware Trojans. We outline the interim stage of our research activities and present our future targets linking chip design and physical verification processes.

2020 Recovery of 2D and 3D Layout Information through an Advanced Image Stitching Algorithm using Scanning Electron Microscope Images
abstract
Image stitching describes the process of reconstruction of a high-resolution image by combining multiple images. Using a scanning electron microscope as the image source, individual images will show patterns in a nm dimension, whereas the combined image may cover an area of several mm2. The recovery of the physical layout of modern semiconductor products manufactured in advanced technologies nodes down to 22 nm requires a perfect stitching process with no deviation with respect to the original design data, as any stitching error will result in failures during the reconstruction of the electrical design. In addition, the recovery of the complete design requires the acquisition of all individually layers of a semiconductor device. The layers represent a 3D structure with interconnections defining error limits on the stitching error for each individual scanned image mosaic. An advanced stitching and alignment process is presented, enabling a true geometrical layout recovery in nanoscale dimensions, which is also applied to and evaluated for other use cases from biological applications.

2019 Integrated flow for reverse engineering of nanoscale technologies
abstract
In view of potential risks of piracy and malicious manipulation of complex integrated circuits built in technologies of 45 nm and less, there is an increasing need for an effective and efficient process of reverse engineering. This paper provides an overview of the current process and details on a new tool for the acquisition and synthesis of large area images and the extraction of a layout. For the first time the error between the generated layout and the known drawn GDS will be compared quantitatively as a figure of merit (FOM). From this layout a circuit graph of an ECC encryption and the partitioning in circuit blocks will be extracted.
