【Abstract】 It is the security that the research of cryptography has been always pursuing as yet. The quantum cryptography, which has made a great deal of progress as the result of a synthesis of ideas from fundamental quantum mechanics and classical encryption, is characterized by the provable security and detection of unauthorized eavesdropping. It provides substantial guarantee for the future cryptographic communication on network with its overcoming of the limitation of the conventional encryption. The paper gives a relative study on the quantum cryptology and the laboratory based model applied, and presents a overall dissertation concerning the quantum key distribution(QKD)protocol. The paper tries to forebode future development in quantum cryptography.更多还原
