Transmission and System Control in Quantum CryptographyKeywords: Quantum Cryptography Abstract: Quantum cryptography provides security using thelaws of quantum mechanics. Currently, several typesof protocols of quantum key distribution (QKD) havebeen established. Some QKD protocols have beencertified by proofs of unconditional security. QKDprotocols have been confirmed to be resistant to anypossible attack. Along with the progress in keytransmission and post processing, the system controlneeds to be integrated with some steps for the QKD.No future technology can break such security. There isa sequence of process for implementing a QKDprotocol. Starting from clock synchronization function,real-time frame synchronization, transmission, postprocessingprotocols to system control and security. Inthis paper we are considering only transmission andsystem control for QKD.
