[U-Boot] U-book and GPLv3? (fwd)

Hi Matthew,

thanks for the explanation.

This is generally not true.  These concepts have well defined meanings.
I can have a secure communicatins channel with someone I did not
authenticate.  Also I can have a non-secure communications channel with
someone who authenticated himself by some means to me.

Running only authenticated code does *not* ensure security, no matter
how much this is wished for.

But no matter, I now understand that "security" seems to mean "data can
only be handled in the way intended by the owners of the data" which is
a different concept to me.

Cheers
