Identity verification in quantum key distribution
Guihua Zeng, Weiping Zhang · Physical Review A · 2000
The security of the previous quantum key distribution protocols, which is guaranteed by the laws of quantum physics, is based on legitimate users. However, impersonation of the legitimate communicators by eavesdroppers, in practice, will be inevitable. In this paper, we proposed a quantum key verification scheme, which can simultaneously distribute the quantum secret key and verify the communicators' identity. Investigation shows that this proposed identity verification scheme is secure.
