In recent decades, human biometrics have been used authenticate the identity of human beings and provide access control. In this paper, we describe the use of Silicon-based “Biometrics” (SIOMETRICS) as the root of trust for Identity Management. This disruptive technological approach is a result of a combination of recent advances in Physical Unclonable Function (PUF) technology, which uses the inherent minute manufacturing variations in semiconductor devices as a silicon “fingerprint,” and advanced identity management techniques. Collaboration between academia, leading industry innovators, and a high assurance security DoD provider has resulted in an architectural approach to change the paradigm in cyber security by reducing the attack surface and total cost of security. This approach is applicable to addressing the supply chain risk management problem by providing a lifecycle chain of custody/trust and securing: content/services (“the Cloud”), Mobile Device Integrity (MDI...
