This Black Hat conference talk explores innovative approaches to key generation in the post-quantum era, examining how to create secure and scalable symmetric keys that can withstand quantum adversaries. Dive into a comparative analysis of various key agreement and distribution methods—from traditional mathematical constructions to quantum-based solutions—evaluated against quantum threat models. Learn about an alternative strategy that leverages finite randomness properties to establish mutual secrecy, offering a quantum-safe method that reimagines security fundamentals. Presented by Frey Wilson, Co-Founder and Chief Technology Officer at Cavero Quantum, this 31-minute briefing provides insights into resilient cryptographic approaches designed to address the challenges posed by emerging quantum computing capabilities.
