There will be no "easy" ways of doing that, ICE and initially ring0 debuggers will still be able to defeat that.

If the bits are in your hardware you'll be able to read them no matter how hard it might be it will still be possible.

A good example will be security tokens, there are quite a few labs that can extract the keys from most common security tokens through various means. This process will cost you anywhere from couple of 1000's of dollars for tokens that are vulnerable to side-channel attacks to hundredths of thousands for tokens that require you to dismantle the IC and probe it directly but for the most part it's still possible.
