Obfuscated Fuzzy Hamming Distance and Conjunctions from Subset Product Problems
Program Obfuscation Hamming Distance Conjunctions
2019/6/4
We consider the problem of obfuscating programs for fuzzy matching (in other words, testing whether the Hamming distance between an nn-bit input and a fixed nn-bit target vector is smaller than some p...
New Techniques for Obfuscating Conjunctions
obfuscation conjunctions learning parity with noise
2018/11/7
We abstract the Bishop et al. scheme to obtain an equivalent yet more efficient "dual'' scheme that can handle conjunctions over exponential size alphabets. This scheme admits a straightforward proof ...
We show how to securely obfuscate the class of conjunction functions (functions like $f(x_1, \ldots, x_n) = x_1 \land \lnot x_4 \land \lnot x_6 \land \cdots \land x_{n-2}$). Given any function in the ...
