Studies in Complexity and Cryptography

A collection of some unpublished works by Oded Goldreich

This collection was compiled in 2010 (and appeared as LNCS 6650, 2011 [See volume's cover]). It consists of revised versions of articles that were not officilally published before, for a variety of reasons. The collection is composed of three types of articles.

  3. O. Goldreich, L.A. Levin, and N. Nisan, On Constructing 1-1 One-way Functions
  4. O. Goldreich and A. Wigderson, On the Circuit Complexity of Perfect Hashing
  5. O. Goldreich, S. Goldwasser, and S. Halevi, Collision-Free Hashing from Lattice Problems
  6. O. Goldreich and D. Zuckerman, Another proof that BPP subseteq PH (and more)
  7. Strong Proofs Of Knowledge
  8. O. Goldreich, S. Vadhan and A. Wigderson, Simplified Derandomization of BPP using a Hitting Set Generator
  9. O. Goldreich and D. Ron, On Testing Expansion in Bounded-Degree Graphs
  10. Candidate One-Way Functions Based on Expander Graphs
  11. Using the FGLSS-reduction to Prove Inapproximability Results for Minimum Vertex Cover in Hypergraphs
  12. The GGM Construction does NOT yield Correlation Intractable Function Ensembles

  15. On the Average-Case Complexity of Property Testing
  16. Z. Brakerski and O. Goldreich, From absolute distinguishability to positive distinguishability
  17. A Candidate Counterexample to the Easy Cylinders Conjecture
  18. L. Avigad and O. Goldreich, Testing Graph Blow-Up
  19. O. Goldreich and T. Kaufman, Proximity Oblivious Testing and the Role of Invariances
  20. In a World of P=BPP
