Abstract
A quantum cryptographic key distribution system (100) includes a first quantum cryptographic device (105b) and a second quantum cryptographic device (105a). The first quantum cryptographic device (105b) is designated as a slave device and stores shared secret bits. The second quantum cryptographic device (105a) is designated as a master device and selects a block of the shared secret bits and notifies the slave device of the selected block of the shared secret bits for using in cryptographically protecting data sent between the first (105b) and second (105a) quantum cryptographic devices.
