  This work shows how a secure Internet can be implemented through a fast key
distribution system that uses physical noise to protect the transmitted
information. Starting from a shared random sequence $K_0$ between two (or more)
users, longsequences $R$ of random bits can be shared. The signals sent over
the Internet are deterministic but have a built-in Nature-made uncertainty that
protects the shared sequences. After privacy amplification the shared $R$
random bits --encrypted by noise-- are subsequently utilized in one-time-pad
data ciphering.
