Abstract
Hardware security has become a critical concern due to the globalization of the Integrated Circuit (IC) supply chain and the complex network connections of computing-intensive devices. Hardware security is essential in the modern world, as more and more connectivity of the Internet of Things (IoT) has paved the way for improvements in personalized healthcare, communication between home (or office) equipment, and the promise of self-driving cars, airplanes, and smart grid systems. As a result, recently, this field has attracted particular attention from the researcher. A significant amount of research has already been conducted to detect, defend, and create resiliency against hardware attacks. This paper investigates different hardware security approaches and state-of-the-art solutions. This paper presents a comparison between the existing methods and outlines their advantages and drawbacks. It provides a comprehensive study of hardware security attacks, and their features, and categorizes different attack types. It also presents the current challenges of hardware security methods and the impact of each one on the security weakness and strengths.
