Lab ideas: Randomness

[dbosk]

• How does the Linux kernel deal with entropy?
• Do the lab experiment of extracting entropy from the phone book. Use Mats' extractor of letters module 29.
• Use min-entropy to evaluate quality.
• Use the tests from the slides: min-entropy and chi-square.
• Use standards NIST SP 800-90B and NIST SP 800-22A and DIEHARD and DIEHARDER.
• Check cryptographic libraries.
• Compare to the hash-function based version.
• Compare to the XOR approach.
• Explore with tests /dev/random and /dev/urandom. Particularly form the perspective Mats pointed out.
• Test PRNGs.
• Try and test the von Neumann trick.
