Multiparty Simultaneous Quantum Identity Authentication Secure against Fake Signal Attacks

Abstract

Multiparty Simultaneous Quantum Identity Authentication (MSQIA) is a form of quantum authentication protocol in which a verifier can simultaneously authenticate all users. Yang et al. previously proposed the MSQIA protocol, but in that protocol the user's key is revealed by the fake signal attack. This paper proposes a new MSQIA protocol that is secure against fake signal attacks. It also demonstrates that this scheme is secure against several well-known attacks on MSQIA. This protocol can be efficiently used for MSQIA in a network and is feasible with current technology, like the protocol of Yang et al.

Multi-party simultaneous quantum identity authentication based on Greenberger-Horne-Zeilinger states

Xing-Fu Wang, Shi‐Pu Gu, Yu‐Bo Sheng +1 more

Abstract A successful implementation of any secure communication protocols requires the identity authentication as a prerequisite. Quantum identity authentication (QIA) can ensure the unconditional security of identity code. In this paper, we propose a multi-party simultaneous quantum identity authentication (MSQIA) protocol based on the Greenberger-Horne-Zeilinger (GHZ) state. In the protocol, N certified users can directly send their identity codes to the authenticator Alice simultaneously through quantum channels without classical communication, which enables Alice to authenticate their identity at the same time. Our protocol only requires Alice to perform the single-photon measurement. In theory, this protocol is unconditionally secure and one pair of ( N + 1)-photon GHZ state can transmit N bits of identity codes. Our MSQIA protocol has application potential in the quantum communication field in the near future.

A New Quantum Multiparty Simultaneous Identity Authentication Protocol with the Classical Third-Party

Xiang Li, Kejia Zhang, Long Zhang +1 more

To guarantee information security in communication, quantum identity authentication plays a key role in politics, economy, finance, daily life and other fields. In this paper, a new quantum multiparty simultaneous identity authentication protocol with Greenberger-Home-Zeilinger (GHZ) state is presented. In this protocol, the authenticator and the certified parties are the participants with quantum ability, whereas the third party is a classical participant. Here, the third-party is honest and the other two parties may be dishonest. With the help of a classical third-party, a quantum authenticator and the multiple certified parties can implement two-way identity authentication at the same time. It reduces the quantum burden of participants and lowers down the trustworthiness, which makes the protocol be feasible in practice. Through further security analysis, the protocol can effectively prevent an illegal dishonest participant from obtaining a legitimate identity. It shows that the protocol is against impersonation attack, intercept-measure-resend attack and entangle-measure attack, etc. In all, the paper provides positive efforts for the subsequent security identity authentication in quantum network.

Simultaneous quantum identity authentication scheme utilizing entanglement swapping with secret key preservation

Arindam Dutta, Anirban Pathak

Unconditional security in Quantum Key Distribution (QKD) relies on authenticating the identities of users involved in key distribution. While classical identity authentication schemes were initially utilized in QKD implementations, concerns regarding their vulnerability have prompted the exploration of Quantum Identity Authentication (QIA) protocols. In this study, we introduce a new protocol for QIA, derived from the concept of controlled secure direct quantum communication. Our proposed scheme facilitates simultaneous authentication between two users, Alice and Bob, leveraging Bell states with the assistance of a third party, Charlie. Through rigorous security analysis, we demonstrate that the proposed protocol withstands various known attacks, including impersonation, intercept and resend and impersonated fraudulent attacks. Additionally, we establish the relevance of the proposed protocol by comparing it with the existing protocols of similar type.

Multiparty quantum communication protocol based on quantum stabilizer codes with identity authentication

J. X. Li, Z. X. He, Shengmei Zhao +2 more

Abstract Quantum communication has been extensively studied and continuously developed due to its theoretical absolute security. In this work, a novel multiparty quantum communication protocol based on quantum stabilizer codes (QSC) is proposed. Firstly, a trusted third party provides quantum identity authentication (QIA) for users. Secondly, users prepare quantum multiparticle entangled states for transmitting secret information. Thirdly, the secret information is encoded by the QSC to resist channel noise. A part of the encoded qubits is selected to detect the security of the communication. In this protocol, QIA prevents active attacks such as impersonation attacks; the physical laws of quantum entangled state ensure information security; the theory of QSC corrects the flipping errors of qubits, and improves the communication efficiency. In addition, we prove the security of the protocol, and further verify the communication efficiency. Compared with existing protocols, this protocol has better performance on communication efficiency.

Two-party quantum identity authentication without entanglement

Yuqi Wang, Liya Jian, Shiming Liu +3 more

This study proposes a two-party quantum identity authentication protocol that does not require the participation of a third party. The protocol can verify the user’s identity without exposing the authentication key information, and it can be implemented with a single-photon state, which does not involve entanglement, enabling it to be combined with existing technologies. The shared key is protected by the protocol and hidden during communication, and the security of the authentication scheme is analyzed and verified under general attack. Further analysis results indicate that this protocol is secure and efficient.
