Abstract: High-security communications against information leakage as well as high-speed communications are realized using present optical fiber networks. The methods are as follows: (1) A seed key is shared between a transmitter and a receiver in advance. Random numbers are transmitted using carrier light accompanied by fluctuations and bases that are decided by random numbers. The transmitter and receiver compare a shared basis that is determined by the seed key with the random basis, and decompose the random numbers superimposed on each bit into two sequences, based on whether the shared basis coincides with the random basis or not. Error correction is processed for each sequence in the receiver, and then the random numbers are shared between the transmitter and the receiver. (2) The amount of the random numbers shared between the transmitter and the receiver is reduced to secret capacity through privacy amplification, and the resultant random numbers are used as a secret key.
