However, for some applications it may suffice that, for every … 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
