Developing a Stochastic Model for a Ring Oscillator and Determination of Correlation Between Ring Oscillators (N22b)
This talk will cover the development of a stochastic model tailored for estimating min-entropy in ring oscillators, essential components in designing secure cryptographic systems. The aim is to bridge the gap between theoretical stochastic processes and their practical application in electrical and computer engineering. The model quantifies the level of randomness, or min-entropy, generated by ring oscillators by encapsulating their unpredictable fluctuations. The discourse will involve examining stochastic modeling principles, applying entropy theories, and demonstrating the process of estimating min-entropy. Attendees will gain insights into leveraging randomness to secure cryptographic devices by understanding the operational mechanics of ring oscillators and applying stochastic principles. Additionally, the talk will explore correlations between multiple ring oscillators in parallel configurations, uncovering potential correlations that may affect system entropy and cryptographic strength. Methodologies and analytical tools for measuring and analyzing these correlations will be discussed, along with strategies to optimize ring oscillator designs for maximum entropy output.
