Obfuscating Point Functions with Multibit Output
We study obfuscation of point functions with multibit output and other related functions. A point function with multibit output returns a string on a single input point and zero ev...

On the Impossibility of Obfuscation with Auxiliary Input
Barak et al. formalized the notion of obfuscation, and showed that there exist (contrived) classes of functions that cannot be obfuscated. In contrast, Canetti and Wee showed how ...

Obfuscation of Hyperplane Membership
Previous work on program obfuscation gives strong negative results for general-purpose obfuscators, and positive results for obfuscating simple functions such as equality testing (...

On obfuscating point functions
We study the problem of obfuscation in the context of point functions (also known as delta functions). A point function is a Boolean function that assumes the value 1 at exactly o...

Collusion Resistant Obfuscation and Functional Re-encryption
Program Obfuscation is the problem of transforming a program into one which is functionally equivalent, yet whose inner workings are completely unintelligible to an adversary. Des...
