Explore the fundamentals and advanced concepts of true random number generators in this 49-minute conference session from CHES 2025, chaired by Michael Pehl. Delve into the critical role of hardware-based randomness in cryptographic systems and security applications. Learn about the design principles, implementation challenges, and evaluation methods for true random number generators that produce unpredictable sequences essential for cryptographic keys, nonces, and other security-critical applications. Examine current research developments, practical considerations for hardware implementation, and the latest techniques for ensuring randomness quality and resistance to attacks. Gain insights into the theoretical foundations of entropy sources, post-processing methods, and statistical testing approaches used to validate true random number generators in real-world cryptographic systems.
