From One-Way Functions to Symmetric Key Encryption || @ CMU || Lecture 25c of CS Theory Toolkit

Definitions of cryptographic pseudorandom generators (PRGs), one-way functions (OWFs), and related concepts. The famous [HILL] Theorem proving that PRGs and hence symmetric key encryption (SKE) can be constructed from (weak) OWFs is mentioned, as are Impagliazzo's Five Worlds. Lecture 25c of "CS Theory Toolkit": a semester-long graduate course on math and CS fundamentals for research in theoretical computer science, taught at Carnegie Mellon University. Resource for this lecture: "A course in cryptography" by Pass and Shelat.
