    $\begingroup$ do you mean white-box cryptography is not a specific method, but some approach? Or some key hiding methods will be considered white-box cryptography and some won't? $\endgroup$ Commented Aug 12, 2011 at 20:31
  • $\begingroup$ @MbyD, yes, that seems about right. In the broadest sense, white-box cryptography is a goal (a security notion we might want to achieve). There have also been some proposed schemes/algorithms for achieving this goal. I'm frequently guilty of conflating "goal" and "scheme", partly because the original papers introducing the concept both defined the general goal and then proposed some schemes intended to achieve that goal. I suspect I've caused confusion by my sloppy use of "white-box cryptography" for both goal and a particular scheme intended to achieve that goal; sorry about that. $\endgroup$ Commented Aug 12, 2011 at 22:15
  • $\begingroup$ BTW, regarding the last link - that's exactly where my question came from... $\endgroup$ Commented Aug 14, 2011 at 9:20
  • $\begingroup$ @D.W. - It's 4.5 years later. Does your answer need any updating or has the state basically stayed the same? Thanks! $\endgroup$ Commented Dec 22, 2015 at 20:25
  • $\begingroup$ @NeilSmithline, everything I wrote still seems valid. There have of course been new results and new developments in obfuscation since then, but nothing that invalidates my answer, as far as I know. For instance, you might enjoy reading about indistinguishability obfuscation. $\endgroup$ Commented Dec 22, 2015 at 20:37
