Book excerpt: This book introduces readers to various threats faced during design and fabrication by today’s integrated circuits (ICs) and systems. The authors discuss key issues, including illegal manufacturing of ICs or “IC Overproduction,” insertion of malicious circuits, referred as “Hardware Trojans”, which cause in-field chip/system malfunction, and reverse engineering and piracy of hardware intellectual property (IP). The authors provide a timely discussion of these threats, along with techniques for IC protection based on hardware obfuscation, which makes reverse-engineering an IC design infeasible for adversaries and untrusted parties with any reasonable amount of resources. This exhaustive study includes a review of the hardware obfuscation methods developed at each level of abstraction (RTL, gate, and layout) for conventional IC manufacturing, new forms of obfuscation for emerging integration strategies (split manufacturing, 2.5D ICs, and 3D ICs), and on-chip infrastructure needed for secure exchange of obfuscation keys- arguably the most critical element of hardware obfuscation.

Book excerpt: "Security is a growing concern in the hardware design world. At all stages of the Integrated Circuit (IC) lifecycle there are attacks which threaten to compromise the integrity of the design through piracy, reverse engineering, hardware Trojan insertion, physical attacks, and other side channel attacks — among other threats. Some of the most notable challenges in this field deal specifically with Intellectual Property (IP) theft and reverse engineering attacks. The IP being attacked can be ICs themselves, circuit designs making up those larger ICs, or configuration information for the devices like Field Programmable Gate Arrays (FPGAs). Custom or proprietary cryptographic components may require specific protections, as successfully attacking those could compromise the security of other aspects of the system. One method by which these concerns can be addressed is by introducing hardware obfuscation to the design in various forms. These methods of obfuscation must be evaluated for effectiveness and continually improved upon in order to match the growing concerns in this area. Several different forms of netlist-level hardware obfuscation were analyzed, on standard benchmarking circuits as well as on two substitution boxes from block ciphers. These obfuscation methods were attacked using a satisfiability (SAT) attack, which is able to iteratively rule out classes of keys at once and has been shown to be very effective against many forms of hardware obfuscation. It was ultimately shown that substitution boxes were naturally harder to break than the standard benchmarks using this attack, but some obfuscation methods still have substantially more security than others. The method which increased the difficulty of the attack the most was one which introduced a modified SIMON block cipher as a One-way Random Function (ORF) to be used for key generation. For a substitution box obfuscated in this way, the attack was found to be completely unsuccessful within a five-day window with a severely round-reduced implementation of SIMON and only a 32-bit obfuscation key."--Abstract.

Book Synopsis Advanced VLSI Design and Testability Issues by : Suman Lata Tripathi

Download or read book Advanced VLSI Design and Testability Issues written by Suman Lata Tripathi. This book was released on 2020-08-18. Available in PDF, EPUB and Kindle. Book excerpt: This book facilitates the VLSI-interested individuals with not only in-depth knowledge, but also the broad aspects of it by explaining its applications in different fields, including image processing and biomedical. The deep understanding of basic concepts gives you the power to develop a new application aspect, which is very well taken care of in this book by using simple language in explaining the concepts. In the VLSI world, the importance of hardware description languages cannot be ignored, as the designing of such dense and complex circuits is not possible without them. Both Verilog and VHDL languages are used here for designing. The current needs of high-performance integrated circuits (ICs) including low power devices and new emerging materials, which can play a very important role in achieving new functionalities, are the most interesting part of the book. The testing of VLSI circuits becomes more crucial than the designing of the circuits in this nanometer technology era. The role of fault simulation algorithms is very well explained, and its implementation using Verilog is the key aspect of this book. This book is well organized into 20 chapters. Chapter 1 emphasizes on uses of FPGA on various image processing and biomedical applications. Then, the descriptions enlighten the basic understanding of digital design from the perspective of HDL in Chapters 2–5. The performance enhancement with alternate material or geometry for silicon-based FET designs is focused in Chapters 6 and 7. Chapters 8 and 9 describe the study of bimolecular interactions with biosensing FETs. Chapters 10–13 deal with advanced FET structures available in various shapes, materials such as nanowire, HFET, and their comparison in terms of device performance metrics calculation. Chapters 14–18 describe different application-specific VLSI design techniques and challenges for analog and digital circuit designs. Chapter 19 explains the VLSI testability issues with the description of simulation and its categorization into logic and fault simulation for test pattern generation using Verilog HDL. Chapter 20 deals with a secured VLSI design with hardware obfuscation by hiding the IC’s structure and function, which makes it much more difficult to reverse engineer.

Book excerpt: Security of integrated circuits (ICs) has emerged as a major concern at different stages of IC life-cycle, spanning design, test, fabrication and deployment. Modern ICs are becoming increasingly vulnerable to various forms of security threats, such as: 1) illegal use of hardware intellectual property (IP) or "IP Piracy"; 2) illegal manufacturing of IC or "IC Piracy"; 3) insertion of malicious circuits, referred as "Hardware Trojan", in a design to cause in-field circuit malfunction, and 4) leakage of secret information from an IC. These security threats are accentuated by current IC design practices, such as the widespread use of hardware IP modules to design complex system-on-chips (SoCs). In addition, the economics of electronic manufacturing dictates widespread outsourcing of integrated circuit fabrication to off-shore facilities, which increases the vulnerability to these attacks. In this research, we explore novel hardware design approaches that incorporate a key-based design obfuscation scheme to effectively protect a design against various security threats, while incurring low hardware and computational overheads. Obfuscation is a technique that makes comprehending and reverse-engineering a design difficult. To the best of our knowledge, this is the first effort to develop a systematic and provably robust hardware obfuscation approach that enables hardware protection at different stages of the IC life-cycle. Effectiveness of these approaches for protection against IP reverse-engineering and piracy, hardware Trojan and scan-based information leakage is evaluated with benchmark circuits and open-source IP cores. The obfuscation approaches are developed for both firm (gate-level) and soft (register transfer level) IPs. The principles of the obfuscation approach have been extended to protection of embedded software against piracy and malicious modification. An enhanced secure IC design flow with associated computer-aided design (CAD) tools is also developed.
