A Practical Guide to Entropy Noise Sources (N20b)
This talk covers both physical and non-physical noise sources utilized for entropy generation. It provides examples of various noise sources, including those based on ring oscillators, metastable latches, CPU jitter, and quantum physics. Additionally, the talk explains the Entropy Source Validation (ESV) certification process, which is a prerequisite for an entropy source to be integrated into a FIPS-certified cryptographic module.
