On Perfect Correctness in (Lockable) Obfuscation
Obfuscation Lockable Obfuscation Perfect Correctness
2019/9/16
In a lockable obfuscation scheme a party takes as input a program PP, a lock value αα, a message mm and produces an obfuscated program P~P~. The obfuscated program can be evaluated on an input xx to l...
On Perfect Correctness without Derandomization
Indistinguishability Obfuscation Correctness Functional Encryption

We give a method to transform any indistinguishability obfuscator that suffers from correctness errors into an indistinguishability obfuscator that is perfectlyperfectly correct, assuming hardness of ...
A Note on Perfect Correctness by Derandomization

2015/12/21
In this note, we show how to transform a large class of erroneous cryptographic schemes into
perfectly correct ones. The transformation works for schemes that are correct on every input
with probabi...
