You are discussing the act of padding an encrypted text so, that there are no peaks in any statistic whatsoever. How about encrypt the whole text, analyze character-frequencies, and sequences of characters, and then pad the text in predefined places with characters that flatten the peaks or create wrong peaks in some sorts of statsistic you would like to apply ? As long as the opponent does not *know* you have added these pads, perhaps this will work ? Other ideas ? gec -- Instruments register only through things they're designed to register. Space still contains infinite unknowns. Germano Caronni caronni@nessie.cs.id.ethz.ch
