Aging resilient ring oscillators for reliable Physically Unclonable Functions (PUFs)
Microelectronics ReliabilityPhysically Unclonable Functions (PUFs) are a promising low-cost solution for authentication and key generation in cryptosystems. However, it has been shown in the literature that, due to aging mechanisms such as Bias Temperature Instability (BTI), PUFs may no longer be able to generate correct outputs after a certain lifetime, thus becoming unreliable.
