I want to know what is the difference between the Key Recovery Attack and the Key Extraction Attack, especially in WhiteBox Cryptography? I guess key recovery is for the BlackBox and key extraction is for the WhiteBox.

    $\begingroup$ I imagine that if there's a firm difference, Key Extraction Attack is a Key Recovery Attack that obtains the key by analysis of the whitebox's code, while Key Recovery Attack obtains the key by any mean, including analysis of intermediary values manipulated by the whitebox while doing it's thing, and/or some amount of iterative key search. That could be 100% wrong, though. $\endgroup$
