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...
Another Step Towards Realizing Random Oracles: Non-Malleable Point Obfuscation
point obfuscation non-malleability virtual black-box
2018/3/7
The random oracle paradigm allows us to analyze the security of protocols and construction in an idealized model, where all parties have access to a truly random function. This is one of the most succ...
Chosen Ciphertext Security via Point Obfuscation
public key encryption lossy encryption key encapsulation mechanism
2016/1/23
In this paper, we show two new constructions of chosen ciphertext secure (CCA secure) public key encryption (PKE) from general assumptions. The key ingredient in our constructions is an obfuscator for...
Indistinguishability Obfuscation versus Multi-Bit Point Obfuscation with Auxiliary Input
indistinguishability obfuscation differing-inputs obfuscation point function obfuscation
2016/1/9
In a recent celebrated breakthrough, Garg et al. (FOCS 2013) gave the first candidate
for so-called indistinguishability obfuscation (iO) thereby reviving the interest in obfuscation for
a general p...
From Point Obfuscation To 3-round Zero-Knowledge
cryptographic protocols / Zero-Knowledge Obfuscation Point Obfuscation Witness-Hiding
2012/3/26
We construct 3-round proofs and arguments with negligible soundness error satisfying two relaxed notions of {\em zero-knowledge}: {\em Weak ZK} and {\em witness hiding} (WH). At the heart of our const...
We show tight connections between several cryptographic primitives, namely encryption with weakly random keys, encryption with key-dependent messages (KDM), and obfuscation of point functions with mul...
