Summary:
Optical devices can be used to generate correlated random bit sequences and that secure key distribution is possible using the correlated random bit sequences. We report the experimental demonstration of a scheme for generating correlated random bit sequences, using semiconductor lasers synchronized by common random optical signals. The correlated random bit sequences generated in this scheme can be used by two legitimate users to create information-theoretically secure keys.
