Candidate Differing-Inputs Obfuscation from Indistinguishability Obfuscation and Auxiliary-Input Point Obfuscation
Indistinguishability Obfuscation Auxiliary-Input Point Obfuscation
2018/11/2
Differing-inputs obfuscation (diO), first proposed by Barak et. al. [4], provides stronger security than that provided by indistinguishability obfuscation (iO). An iO scheme provides indistinguishabil...
We provide the following negative results for differing-inputs obfuscation (diO): (1) If subexponentially
secure one-way functions exist then sub-exponentially secure diO for TMs does
not exist (2) ...

Differing inputs obfuscation (diO) is a strengthening of indistinguishability obfuscation (iO) that
has recently found applications to improving the efficiency and generality of obfuscation, function...

The notion of differing-inputs obfuscation (diO) was introduced by Barak et al. (CRYPTO 2001). It guarantees that, for any two circuits $C_0, C_1$, if it is difficult to come up with an input $x$ on w...
In this paper we study of the notion of differing-input obfuscation, introduced by Barak et al. (CRYPTO 2001, JACM 2012). For any two circuit C_0 and C_1, differing-input obfuscator diO guarantees tha...
