You are basically saying the adversary controls the inputs of both black boxes (one of them is ideal black box and the other is real black box). So when the adversary pushes buttons and messes with the inputs he/she still can't tell the differences between real and ideal black box. Thus they won't be able to crack the code and get to the secret state inside the black box? | |
