Abstract

Using the quantum teleportation and quantum entanglement swapping, a quantum identification scheme of Cross-center based on W-state is proposed, and the identification for user in distributed network is realized. The scheme includes register phase and authentication phase, and the whole system consists of main server and client server. All the operations of any user are 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 analyzed.

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.

Wenjie Liu, Hanwu Chen, Zhihao Liu +1 more

In this paper, an authenticated deterministic secure quantum communication protocol based on entanglement swapping is presented. The users' identity will be authenticated, and only legitimate users can anticipate the communication even though there are no quantum communication channels between them. The authentication center acts as the server of modern application system, and the users is like those clients linked with the server, then the users communicate with each other through the authentication center. The security of our protocol is analyzed to be secure against the eavesdropping attacks and the impersonation attack.

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.

Secure quantum cryptographic network based on quantum key distribution

Sora Choi, Soojoon Lee, Dong Pyo Chi

We present a protocol for quantum cryptographic network consisting of a quantum network center and many users, in which any pair of parties with members chosen from the whole users on request can secure a quantum key distribution by help of the center. The protocol is based on the quantum authentication scheme given by Barnum et al. [Proc. 43rd IEEE Symp. FOCS'02, p. 449 (2002)]. We show that exploiting the quantum authentication scheme the center can safely make two parties share nearly perfect entangled states used in the quantum key distribution. This implies that the quantum cryptographic network protocol is secure against all kinds of eavesdropping.
