That's certainly one of the problems, yes. Another is that I rushed the 
whole cryptosystem through from conception through software 
implementation to publication for competitive peer review in about 
twelve minutes all told. So I cannot guarantee that other problems may 
not also become apparent. (I can reveal, for example, that my decryption 
code does a workmanlike but less than stellar job and isn't about to win 
any prizes.)

I can report one important theoretical discovery about the system: it 
turns out *not* to be informational-theoretically secure. Who'd ha' 
thunk it, eh?
