  This work shows how a secure Internet for users A and B can be implemented
through a fast key distribution system that uses physical noise to encrypt
information transmitted in deterministic form. Starting from a shared secret
random sequence between them, long sequences of fresh random bits can be shared
in a secure way and not involving a third party. The shared decrypted random
bits -encrypted by noise at the source- are subsequently utilized for
one-time-pad data encryption. The physical generated protection is not
susceptible to advances in computation or mathematics. In particular, it does
not depend on the difficulty of factoring numbers in primes. Also, there is no
use of Linear Feed Back Shift Registers. The attacker has free access to the
communication channels and may acquire arbitrary number of copies of the
transmitted signal without lowering the security level. No intrusion detection
method is needed.
