Two kinds of quantum key distribution protocols which based on different property of quantum mechanics are discussed in this paper. The security of both categories are proved, especially the security of quantum key distribution in the condition of existing a probabilistic cloning machine. It was shown that the quantum bit error rate which Alice and Bob estimated after sifted key reduced to 21% in probabilistic cloning scheme.

加密算法的安全性是保证信息机密性、完整性和可用性的基础。与经典的加密算法不同,量子加密算法具有完全可证明的安全性。本文介绍量子密钥分配协议模型,并针对存在概率克隆机的理论,证明了基于不可克隆原理的量子密钥分配协议具有足够的安全性。

We study the error rate of quantum key distribution (QKD) through noisy quantum channel, and we get the relationship between the quantum bit error rate (QBER) a nd the fidelity of the noisy channel. Basing on the local distinguishing princip le, we propose a scheme of QKD through the symmetric noisy quantum channel that can get secret keys without errors as using the maximally entangled states (the four Bell states) through pure quantum channel.

Unlike classical bits, quantum bits cannot be duplicated and the quantum-entangled states cannot be identified. This property of quantum information was used to suggest an information-theoretic secure cryptography-quantum cryptography. This paper concentrates on quantum key distribution over a long-distance quantum network, it has many nodes and control centers which are connected by quantum channels. Quantum bits are storage on the quantum control centers and using entanglement states swapping to transfer over large distances between nodes and centers. An eavesdropper will inevitably increase the quantum bit error rate and the legitimate users will detect the eavesdropper and hence not use the key.

在传统的点到点之间进行量子密钥分发协议的基础上,利用量子存储技术和EPR粒子纠缠态互换的方法,提出了在多用户、多控制中心、远距离的网络环境下进行量子密钥传送的方案。与传统的点与点之间的量子密钥传送协议类似,其安全性也是建立在量子力学原理上,任何窃听者的存在必将使生成密钥的误码率上升而被合法通信用户发现。
