Quantum Key Distribution was named as one of the top
ten emerging technologies by Technology Review
Journal in 2003. The growth in quantum cryptography
since the beginning of the millennium has been
expedited by new theories and ideas.
When Bennett and Brassard proposed their BB84
protocol in 1984, no one would have guessed the
quantum revolution they had launched. Since then,
new protocols have been proposed and new theories
developed, but BB84 remains the simplest and
probably the easiest to implement. Now that the
practical implementation of basic quantum
cryptography has been achieved, one can be almost
certain that new protocols will sooner or later be
tested for the efficiency they could provide. We
have developed a Classical Authentication Aided
(CAA) protocol, which merges the classical
authentication policies with quantum transmission to
make it even more secure. With the complexities of
the authentication policies and the bit to qubit
conversion, our system becomes a complex one. We
also discuss the possibilities of free space quantum
transmission of the protocol instead of only through
optical fiber.
