利用纠缠态进行量子认证

Quantum authentication using entangled state

Yong-Sheng Zhang, Chuan-Feng Li, Guang-Can Guo

摘要:

提出了一种量子认证方案。双方共享Einstein-Podolsky-Rosen(EPR)对作为认证密钥,作为编码器和解码器。认证是通过本地控制非操作和酉旋转来完成的。证明了该方案即使在窃听者完全控制经典信道和量子信道的情况下也是安全的。该协议的另一个特点是EPR源是可重用的。该协议的鲁棒性也进行了讨论。

英文摘要:

A scheme of quantum authentication is presented. Two parties share Einstein-Podolsky-Rosen (EPR) pairs previously as the authentication key which servers as encoder and decoder. The authentication is accomplished with local controlled-NOT operations and unitary rotations. It is shown that our scheme is secure even in the presence of an eavesdropper who has complete control over both classical and quantum channels. Another character of this protocol is that the EPR sources are reusable. The robustness of this protocol is also discussed.
