A New Approach to /dev/random

Explore a new approach to /dev/random in this 45-minute conference talk by Stephan Mueller from atsec information security GmbH. Delve into the Linux Random Number Generator (LRNG) goals, design, and output APIs. Learn about managing drng instances, cryptographic primitives, and various entropy sources. Examine the internal entropy source, processing side, health tests, and oversampling techniques. Gain insights into the testing procedures and conclude with a comprehensive understanding of this innovative approach to random number generation in Linux systems.
