Building and Testing Entropy Sources for Cryptography
When designing cryptographic Random Bit Generators (RBGs), it is essential to understand how they are tested, certified, and used in high-security chips and applications. After a bit of history and relevant theory, I'll be covering common physical noise source and entropy source designs and how RBGs are constructed from those. Emphasis is on current and upcoming U.S. (FIPS / NIST) and International (Common Criteria) key generation standards for high-security applications, and also attacks, defenses, and research challenges that go a bit beyond those requirements.
