Phys. Rev. A 61, 022303 (2000) [5 pages]Identity verification in quantum key distributionReceived 30 April 1999; published 6 January 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. © 2000 The American Physical Society URL:
