Universal One-Way Hash Functions via Inaccessible Entropy

Speaker: Hoeteck Wee Queens College, CUNY
Time: 2010-04-01 14:00-2010-04-01 15:00
Venue: FIT 1-222

Abstract:

In this talk, we will revisit the construction of Universal One-Way Hash Functions (UOWHFs) from any one-way function due to Rompel (STOC 1990). I will present a simpler construction of UOWHFs, which also obtains better efficiency and security. The construction exploits a strong connection to the recently introduced notion of inaccessible entropy (Haitner et al. STOC 2009).
Based on joint work with Iftach Haitner (Microsoft Research), Thomas Holenstein (ETH Zurich), Omer Reingold (Weizmann and Microsoft) and Salil Vadhan (Harvard), to appear in Eurocrypt 2010.
