Abstract

Using the two times quantum teleportation,a quantum identification scheme of cross-center based on four-qubit cluster state is proposed,and the identification for user in distributed network is realized.In this scheme,the identification system consists of main server and client server,and the communication between main server and client server is performed using the four-qubit cluster state as quantum channel. All the operations of any user axe processed at client server and there is no direct communication between user and main server.All authentications are processed by servers based on the principles of quantum mechanics,and its security is guaranteed by quantum mechanism.Finally,the security of the quamtum identification scheme is analysed.

Cross-center Quantum Identity Authentication Scheme Based on Teleportation

Wenjie Zeng, Guihua Zeng

A cross-center quantum identity authenticatin scheme was proposed.Which was based on teleportation and quantum entanglement swapping in quantum optics.In a distributed network,the proposed scheme was realized by transmitting information in quantum channel using shared EPR pairs and exchanging necessary information in classical channel at the same time.The security of this scheme,which is guaranteed by quantum mechanism,is unconditional as the EPR quantum key distribution protocol.Compare with previous schemes,the proposed scheme overcomes some disadvantages of those simple point-to-point quantum identity authentication scheme.Because of the characteristic of cross-center extending the authentication range,the proposed scheme is more flexible and practical.

An efficient deterministic secure quantum communication scheme based on cluster states and identity authentication

Wenjie Liu, Hanwu Chen, Tinghuai Ma +3 more

A novel efficient deterministic secure quantum communication scheme based on four-qubit cluster states and single-photon identity authentication is proposed. In this scheme, the two authenticated users can transmit two bits of classical information per cluster state, and its efficiency of the quantum communication is 1/3, which is approximately 1.67 times that of the previous protocol presented by Wang et al [ Chin. Phys. Lett. 23 (2006) 2658]. Security analysis shows the present scheme is secure against intercept-resend attack and the impersonator's attack. Furthermore, it is more economic with present-day techniques and easily processed by a one-way quantum computer.

Quantum Teleportation of Arbitrary Two-qubit State by using a Four-qubit Cluster State

Yin Yi-fe

In order to complete the quantum teleportation,we propose a quantum teleportation scheme of arbitrary twoqubit cluster state by using a four-qubit cluster state based on quantum entanglementphenomenon in this paper. In this scheme,the sender and the receiver share a four-qubit cluster state. The sender first performs a joint von-Neumann measurement on the qubits in his hand. And he sends the measurement results to the receiver through the classical channel. The receiver performs corresponding unitary operation according to the measurement results he received. In the process of this communication,the sender does not tell the original arbitrary two-qubit cluster state to the receiver,but he reconstructs the arbitrary two-qubit state. The quantum teleportation comes true through these processes and the mutual communication is completed.

Quantum information query scheme based on quantum teleportation

Daicao Wan, Meng Jing, Mengdie Li +2 more

With the deep penetration and iteration of network technology, the realization of secure and controlled information query is related to the confidentiality, integrity and availability of data resources. In this paper, a quantum information query scheme based on quantum teleportation is proposed by combining quantum teleportation and information query. In this scheme, the user transmits the query information while performing two-way authentication with the access controller to verify the legitimacy of the user, and then the information is sent to the data processing center using quantum teleportation and the correctness of the signature is verified, and then the system performs the retrieval operation. The scheme is characterized as follows: synchronization of authentication and encryption is achieved by integrating the authentication bits and encrypted information bits into the same quantum sequence by using bi-directional authentication in non-orthogonal states and bit-folding techniques; By implementing localized unitary operations on the shared EPR entangled states, the verification information is encoded in the quantum correlation properties between particles, forming a novel communication architecture for transmitting information through particles invisibly; The security analysis shows that the scheme is non-forgeable, non-repudiation and traceable, as well as resistant to intercept-retransmit attacks and Denial-Of-Service (DOS) attacks.

Quantum Identity Authentication Based on Network

Bin Liu

Two quantum identity authentication schemes based on communication network scale are proposed.One is to authenticate directly,the other is to authenticate based on the Authentication Server(AS).A characteristic in the proposal is that the authentication key can be obtained dynamically.The proposal can be realized easier.The security is guaranteed by the no-cloning theory and the dynamical features of the proposed scheme.
