Interesting - but I wonder if the chaff generation can easily be automated: in order to fulfill its function (hiding the wheat), the chaff must be closely adapted to the specific valid content. It cannot be nonsensical, otherwise it would be recognised.

>>easily automated<<
What if every word, or part thereof, were keyed?

A couple of four years ago, the Economist ran a piece about quantum encryption, where the key would be completely random from the point of view of everyone but the sender and the recipient. Seems smaller, simpler and more elegant to me. (Not that the whole topic of quantum mechanics isn't a bit random to this Druid).

If I understand this correctly after a cursory glance, it hardly seems new. I'm sure I've heard of messages being sent long before computerisation where only certain words (say every 10th word or the third word on each line) were part of the real message and then an innocuous sounding message was written round those words to hide them.

You're right, of course, Bing - the 'mask over the text' approach and similar (is there a specific word for that?) - this is just an updated implementation of the unscrambling of chaff and kernel.
