  • Hardware Trojans – Prevention, Detection, Countermeasures (A Literature Review)
    UNCLASSIFIED Hardware Trojans – Prevention, Detection, Countermeasures (A Literature Review) Mark Beaumont, Bradley Hopkins and Tristan Newby Command, Control, Communications and Intelligence Division Defence Science and Technology Organisation DSTO–TN–1012 ABSTRACT A Hardware Trojan is a malicious, undesired, intentional modification of an electronic circuit or design, resulting in the incorrect behaviour of an electronic device when in operation – a back-door that can be inserted into hardware. A Hardware Trojan may be able to defeat any and all security mechanisms (software or hardware-based) and subvert or augment the normal operation of an infected device. This may result in modifications to the functionality or specification of the hardware, the leaking of sensitive information, or a Denial of Service (DoS) attack. Understanding Hardware Trojans is vital when developing next generation de- fensive mechanisms for the development and deployment of electronics in the presence of the Hardware Trojan threat. Research over the past five years has primarily focussed on detecting the presence of Hardware Trojans in infected devices. This report reviews the state-of-the-art in Hardware Trojans, from the threats they pose through to modern prevention, detection and countermeasure techniques.

    INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 9, ISSUE 06, JUNE 2020 ISSN 2277-8616 Reduction Of Hardware Trojan Effect Using Multipath Authentication P. Bosebabu, K. Siva Nagaraju, B. Chanikya, P. Ritish Kumar Abstract: with increase of Integrated Circuit (IC) manufacturing foundries and fabrication units, security of an IC gains its importance. The manufacturing of IC is having many stages like designing, assembling, packaging, etc. Hardware Trojans can be implantable at any of these stages by the foundries or third-party vendors. Hardware Trojan is a malicious, undesired, intentional, modification of an electronic circuit or design, resulting leakage of data or incorrect behaviour of an electronic device. The Cryptographic algorithms play an important role in information security and protection of data from unauthorised usage. The proposed AES crypto processor model is having a authentication monitoring which will detect hardware Trojan triggering, alerts the user and takes necessary actions for retrieving original data. With help of proposed system, the reduction of effect of hardware Trojan can be achievable. Keywords: Hardware Trojan, Cryptography, IC security, AES. ———————————————————— 1. INTRODUCTION 2.

  • Hardware Security and Trust: a New Battlefield of Information
    Hardware Security and Trust: A New Battlefield of Information Gang Qu University of Maryland, College Park, MD 20742, USA [email protected] Abstract. Hardware security and trust has received a lot of attention in the past 25 years. The purpose of this paper is to introduce the fundamental problems related to hardware security and trust to audiences who do not necessarily have hardware design background. In order to do that, we first discuss the evolving roles of hardware in security from an enable to an enhancer and now an enforcer as it get involves more and more in system security. Then we review the following key problems in hardware security, physical attacks, side channel analysis, intellectual property protection, hardware Trojan, hardware security primitives, and applications in security and trust. We provide a novel view of these problems and the corresponding solutions from the perspective of information battle between the attackers and designers, where we consider three types of information: data collected, processed, and stored by the hardware; information hidden in the design as watermark, fingerprint, and Trojans; and the chip fabrication variations that can be extracted and utilized. It is interesting to see how the hardware security and trust problems can be unified under this framework of information battle (stealing and protection). Unfortunately, there are more unknowns and challenges than what we have discovered on this framework as we illustrated in the section of open problems. However, the emerging Internet of Things and cyber physical systems have provided a large application field for researchers and practitioners to work on hardware based lightweight security.

J I N , EECS Department, University of Central Florida R. KARRI, ECE Department, Polytechnic Institute of New York University S. BHUNIA and M. TEHRANIPOOR, ECE Department, University of Florida Given the increasing complexity of modern electronics and the cost of fabrication, entities from around the globe have become more heavily involved in all phases of the electronics supply chain. In this environment, hardware Trojans (i.e., malicious modifications or inclusions made by untrusted third parties) pose major security concerns, especially for those integrated circuits (ICs) and systems used in critical applications and cyber infrastructure. While hardware Trojans have been explored significantly in academia over the last decade, there remains room for improvement. In this article, we examine the research on hardware Trojans from the last decade and attempt to capture the lessons learned. A comprehensive adversarial model taxonomy is introduced and used to examine the current state of the art. Then the past countermeasures and publication trends are categorized based on the adversarial model and topic. Through this analysis, we identify what has been covered and the important problems that are underinvestigated. We also identify the most critical lessonsr for those new to the field and suggest a roadmap for future hardware Trojan research.

  • Hardware Trojan Identification and Detection
    International Journal on Cryptography and Information Security (IJCIS), Vol. 7, No. 2, June 2017 HARDWARE TROJAN IDENTIFICATION AND DETECTION Samer Moein 1, Fayez Gebali 1, T. Aaron Gulliver 1, And Abdulrahman Alkandari 2 1Department of Electrical and Computer Engineering, University of Victoria, Victoria, BC, Canada 2Department of Computer Science, Public Authority for Applied Education and Training, Kuwait City, Kuwait ABSTRACT The majority of techniques developed to detect hardware trojans are based on specific attributes. Further, the ad hoc approaches employed to design methods for trojan detection are largely ineffective. Hardware trojans have a number of attributes which can be used to systematically develop detection techniques. Based on this concept, a detailed examination of current trojan detection techniques and the characteristics of existing hardware trojans is presented. This is used to develop a new approach to hardware trojan identification and classification. This identification can be used to compare trojan risk or severity and trojan detection effectiveness. Identification vectors are generated for each hardware trojan and trojan detection technique based on the corresponding attributes. Vectors are also defined which represent trojan risk or severity and trojan detection effectiveness. KEYWORDS Hardware trojan detection, hardware trojan identification, trojan severity, trojan risk, trojan detection effectiveness 1. INTRODUCTION With the increasing globalization of Integrated Circuit (IC) design and production, hardware trojans have become a serious threat to manufacturers as well as consumers. The use of ICs in critical applications makes the effects of these trojans a very dangerous problem. Unfortunately, the use of untrusted foundries and design tools cannot be eliminated since the complexity of ICs and the sophistication of their manufacture has grown significantly.
