I think that in your scenario, the encrypted information was
transmitted at faster than light speed.

OK. In this case, the part of the system that transmits
encrypted information at ftl speed indeed works, but the system
as a whole can't transmit useful information at ftl speed, so I
would say it doesn't 'work', or doesn't have an obvious
practical application.

Yes, the limit of c is violated, but I don't think that is a
problem, because contrary to 'scientific' dogma, I don't
believe there must be an absolute (haha!) maximum speed that
moving objects can't exceed.
Now, although your hypothetical scenario makes sense, the
question remains : do entangled particles actually behave like
in your scenario?
(I'll do some searching tomorrow, see what comes up)
