As far as terminology goes.. what about something like Shamir's threshold
scheme? I've seen sites/messages that say the OTP is the only unbreakable
cipher, and I've seen others that lump the OTP and threshold schemes
together.
I tend to think of the OTP/Vernam cipher as a special case of Shamir's
threshold scheme.. namely the case where you only what one share issued,
but I still have problems with equating the two..
The only term I'm aware of that covers both is a 'perfect cipher' .. which
has other problems ;) .. anyone know of a better term?
