论文摘要
纠缠测量攻击是量子密码学中众所周知的攻击。在量子加密协议中,窃听检查可以抵抗此攻击。有两种已知的窃听检查方法。一种是使用诱饵光子技术进行窃听检查。另一个是使用两组非正交纠缠状态的纠缠相关性进行窃听检查。在本文中,我们证明了针对基于QUDIT系统的量子加密协议的纠缠测量攻击的安全性,该量子使用了两种方法进行窃听检查。我们的安全性证明对于改善量子加密协议中使用的窃听检查方法很有用。
Entanglement-measurement attack is a well-known attack in quantum cryptography. In quantum cryptography protocols, eavesdropping checking can resist this attack. There are two known eavesdropping checking methods. One is to use decoy photon technology for eavesdropping checking. The other is to use the entanglement correlation of two groups of non-orthogonal entangled states for eavesdropping checking. In this paper, we prove the security against entanglement-measurement attack for the qudit-system-based quantum cryptography protocols which use the two methods for eavesdropping checking. Our security proof is useful to improve the eavesdropping checking method used in quantum cryptography protocols.
