Abstract

International Association for Cryptologic Research 2015.

Assuming trapdoor permutations, we show that there exist function families that cannot be VBB-obfuscated even if both the obfuscator and the obfuscated program have access to a random oracle. Specifically, these families are the robust unobfuscatable families of [Bitansky-Paneth, STOC 13]. Our result stands in contrast to the general VBB obfuscation algorithms in more structured idealized models where the oracle preserves certain algebraic homomorphisms [Canetti-Vaikuntanathan, ePrint 13; Brakerski-Rothblum, TCC 14; Barak et al., Eurocrypt 14].
