Introduction:

As more people and places throughout the world connect to the internet, it is more important than ever to make sure that physical systems are secure. Very Large-Scale Integration, or VLSI for short, is an important part of the process of developing complicated hardware designs including microprocessors, Internet of Things devices, and embedded systems. However, new obstacles for hardware security have arisen as a result of an increase in the sophistication of cyber attacks and a growth in the complexity of hardware design. Within the context of VLSI design, we will investigate the new issues that are arising in the field of hardware security in this blog post.

Conclusion:

The topic of hardware security in very large scale integrated circuit (VLSI) design is facing expanding issues as a result of the increasing complexity of hardware systems and the emergence of sophisticated cyber threats. Protecting sensitive data and maintaining the integrity of the system is dependent on properly securing the hardware designs, resolving any vulnerabilities that may exist in the supply chain, and minimising any threats that may arise, such as side-channel attacks and Trojans. As new technologies such as quantum computing, artificial intelligence, and the internet of things (IoT) continue to develop, collaborative efforts between industry stakeholders, academic communities, and research communities will play an essential role in addressing these challenges and advancing hardware security to protect our increasingly interconnected world.
