it would be called the "purple box" because I have not heard of any other devices called "purple boxes" (i.e. this string in the "colorful" hacker namespace does not seem to be used up yet) and also the famous WWII compromised japanese diplomatic codes were called Purple.
Actually quite a few hackers/phreaks have been encrypting phone conversations for a while. Not by any complex mathematics but simple modifications to the phone frequencies...Don't have any sites handy but for those interested I'll look up some of my old material. I'll also check a large compendium of boxes to see if Purple has been designated. Anyone interested in box plans of different colors e-mail me.
