Witrynaobfuscated program cannot do better than a simulator that is given only black-box access to the program. Barak et al. constructed contrived function families that cannot be VBB obfuscated, thus ruling out a universal obfuscator, but they left open the possibility that large classes of programs might still be obfuscated.

Furthermore, it was shown by [39] that iOis, in fact, \best-possible" obfuscation. iOhas already enabled a long sequence of Witrynaobfuscation. Informally, a program is VBB obfuscated if an attacker can learn nothing more, when given the executable code, than what could be learned from running it (i.e., oracle access). This is a very strong notion that captures the intention of \hiding semantic properties of program code". But unfortunately, Barak et
