One tidbit here; the Queen of the UK and a score of other
nations keeps her own crypto machines jealously guarded and
the UK is not involved, except as consultants for the 
secrecy.

The royals operate the cipher machines themselves, and no
servants are allowed in the room while this happens. This
is very unusual for royals; they usually have servants
doing everything for them.

The rationale is that she needs secure channels to all
her subject nations, none of which should eavesdrop on any
other.
