There is an amusing story about SCOMP. SCOMP was designed to get
an A1 security rating, and after jumping through all the hoops
actually received that rating. Somewhat after that, someone
discovered a quite high bandwidth covert channel in SCOMP. One
of the developers was heard to quip, "I don't want to call is
secure. I just want to call it A1."
