The weakness is that the row digits never appear as column digits. The classical Straddling Checkerboard does not have this weakness. I've just started reading through Friedman & Callimahos' "Military Cryptanalytics." I noticed it had a chapter on monome-dinome ciphers, and discussed quite a few, including the Straddling Checkerboard. None of the monome-dinome variants discussed had this weakness. Given the general level of expertise of the folks in the ACA who standardized on these ciphers, I can only presume that this weakness was intentional - to give novices who are just moving beyond the Aristos a place to start. Much like the ACA's homophonic cipher - far easier to crack than a generic homophone. Quote: I've become a member of the ACA too Welcome.
