Internet of Things World: A New Security Perspective

The Internet of Things (IoT) is changing and transforming how we interact with the physical world. IoT devices have had widespread applications in many fields of production and social living, such as healthcare, energy and industrial automation, and military application, to name a few. While we can’t deny the benefits of IoT, like convenience, accessibility, and efficiency, it is a double-edged sword. The security aspect remains a significant concern in the IoT realm, especially physical attacks since there are abundant channels due to physical effects. Much research focuses on software, network, and cloud security; however, hardware security in these devices has been overlooked. Considering this motivation, in this survey, first, we provide the recent advancement in the physical attack defense techniques and extend the literature to summarize the unified countermeasures that benefit IoT devices to address the footprint and power constraints. We also discuss some open problems that need attention. Further, to defeat the IoT system from advanced hardware attacks, we proposed to use 3D integration as a key enabling IoT platform. 3D technology provides various advantages, such as heterogeneous integration, split manufacturing, and disparate technologies like MEMS sensors, making 3D integration the best choice for IoT platforms.
