Weban indistinguishability obfuscator for a circuit class {C λ}if: (1) it preserves the input-output behavior of the unobfuscated circuit and (2) given two circuits C 1,C 2 ∈C λ and … Web5 feb. 2014 · For this application indistinguishability obfuscation suffices, since by definition a version restricted in the interface is indistinguishable from an obfuscated program with equivalent behavior that has its smarts removed at the start. The use case is dubious, at best.

Indistinguishability Obfuscation from Functional Encryption - IACR

WebIn this work, we study the notion of indistinguishability obfuscation (iO) for general polynomial-size circuits [BGI+01a, GKR08, GGH+13b]. iOrequires that for any two cir … WebThis paper studies the question of how to define, construct, and use obfuscators for probabilistic programs. Such obfuscators compile a possibly randomized program into a deterministic one, which achieves computationally indistinguishable behavior from the original program as long as it is run on each input at most once. range calculator byjus https://new-lavie.com

A program obfuscator takes a program and outputs a “scrambled” version of it, where the goal is that the obfuscated program will not reveal much about its structure beyond what is apparent from executing it. There are several ways of formalizing this goal. Specifically, in indistinguishability obfuscation, first defined by Barak et al. …
