Chaff, by analogy with the radar-jamming aluminum strips used by the
allies in WWII, I assume.  Or maybe just the conventional meaning of
chaff (the junk left over when you winnow grain).

I don't immediately see how this alters my claim that by using
cryptography to prevent leakage, you also prevent interesting
processing.
