Witryna1 lis 2015 · ally, an obfuscated program should be a “virtual black box,” in the sense that anything one can compute from it one could also compute from the input-output behavior of the program. The hope that some form of obfuscation is possible arises from the fact that analyz-ing programs expressed in rich enough formalisms is hard. … Witrynaobfuscated program is a “virtual black box.” That is, anything one can eﬃciently compute from the obfuscated program, one should be able to eﬃciently compute given just oracle access to the program.
