Analog Security and Protection
Hardware security has emerged as a critical concern in modern electronics as integrated circuits become increasingly complex and supply chains span multiple countries and organizations. Analog circuits, long considered inherently secure due to their complexity and the difficulty of reverse engineering continuous-time systems, have become attractive targets for malicious modifications precisely because traditional security measures focus predominantly on digital logic.
The protection of analog circuits encompasses multiple disciplines: detecting unauthorized modifications known as hardware Trojans, implementing tamper-resistant designs, authenticating genuine components, and establishing trust throughout the design and manufacturing process. These security measures become essential in applications ranging from military and aerospace systems to medical devices, financial infrastructure, and critical communications equipment where circuit integrity directly impacts safety and national security.
