New Negative Results on Differing-Inputs Obfuscation

Mihir Bellare, Igors Stepanovs, and Brent Waters

Abstract

We provide the following negative results for differing-inputs obfuscation (diO): (1) If sub-exponentially secure one-way functions exist then sub-exponentially secure diO for TMs does not exist (2) If in addition sub-exponentially secure iO exists then polynomially secure diO for TMs does not exist.
