-----BEGIN PGP SIGNED MESSAGE----- I'm wondering if anyone has done any work on schemes to lower the entropy of a given stream. Why? Save you've got message M encrypted with a good cipher, but you're worried that it can be detected because even with stego, the entropy is a lot higher than normal 'random' data flowing through a network. So it seems possible to create a scheme that given a key will take a block of n bits and expand it to 1.5n or 2n bits, recoding it in such a way that determining the key is difficult even if one suspects such a scheme has been used... but that using the scheme will make the data look more like the MSBs of graphical data rather than encrypted data.
