Information security has emerged as an important system and application metric. Classical security solutions use algorithmic mechanisms that address a small subset of emerging security requirements, often at high energy and performance overhead. Further, emerging side channel and physical attacks can compromise classical security solutions. Hardware based security solutions overcome many of the limitations of classical security while consuming less energy and improving performance. Nanoelectronics based hardware security preserves all of these advantages while enabling conceptually new security mechanisms and security applications. This paper highlights nanoelectronics based security capabilities and challenges.
