Bad Randomness - Protecting Against Cryptography's Perfect Crime

Explore the critical vulnerability of bad randomness in cryptographic systems through this 39-minute Black Hat conference talk. Delve into how compromised randomness can completely undermine crypto systems while remaining undetectable. Examine real-world examples, including the APT Reductor malware's ability to break TLS encryption and Bitcoin's "dark forest" bots exploiting weak signature keys. Learn about a novel architecture that minimizes reliance on randomness and implements secure Multi-Party Computation to enhance system resilience. Gain insights into protecting against this stealthy threat and understand its implications for digital security infrastructure.
