Information leakage in quantum dialogue by using the two-qutrit entangled states

Abstract

In this paper [Mod. Phys. Lett. B23 (2009) 2993], Zhang and Zhan proposed a quantum dialogue protocol by using the two-qutrit entangled states. We study the security of the protocol and find that it is not secure. The eavesdropper can obtain half of secret messages without performing any attack. In other words, their quantum dialogue protocol has the drawback of information leakage.

Two quantum dialogue schemes based on Bell states and two-qutrit entangled states without information leakage

Zhu Zhenchao

Drawing on the idea of the quantum secure direct communication(QSDC),a novel quantum dialogue scheme based on Bell states is presented in this paper.The proposed scheme can realize authorized parties' secure exchange of their respective secret messages simultaneously only through one communication.In this scheme,a random bit string and checking particles are used to ensure the security;the scheme is secure against eavesdropper's commonly used attacks,such as intercept/resend attack,Trojan horse attack and entanglement attack.A serious problem called leakage or correlation is found in some quantum dialogue protocols,namely,any eavesdropper can elicit some information about the secret from the classical communication of the legal users.Fortunately,our protocol can discard the drawback leakage.In addition,our protocol possesses high efficiency 66.7% and is feasible.Finally,the protocol is applied to the scheme based on two-qutrit entangled states with a secure communication.

Information Leakage in Quantum Dialogue by Using Non-Symmetric Quantum Channel*

Gan Gao, Wei-Yan 伟艳 Li 李, Yue Wang

Abstract In this paper [Commun. Theor. Phys. 53 (2010) 648], Zhan et al. proposed a quantum dialogue protocol by using non-symmetric quantum channel. We study the security of the protocol and find that it has the drawback of information leakage. That is, Zhan et al.ʼs protocol is proved to be insecure by us.

Quantum Dialogue Revisited

Man Zhong-Xiao, Zhanjun Zhang, Yong Li

An entanglement-based quantum dialogue protocol [Phys. Lett. A 328 (2004) 6] is proven to be insecure: that is, in the protocol an eavesdropper can steal the secret messages without being detected provided that he/she adopts the intercept-and-resend attack strategy. We modify the protocol, i.e. in the control mode, by introducing and randomly choosing two sets of measuring basis: the intercept-and-resend attack can be accordingly detected. Hence, within the present version two users can securely and simultaneously exchange their secret messages.

Quantum Dialogue Without Information Leakage via Cavity QED

YE Tian-y

Good security is indispensable to any quantum secret communication protocol.However, information leakage has been a great security threat to quantum dialogue.In order to solve the problem,aquantum dialogue protocol without information leakage via cavity QED was proposed, which made full use of the evolution law of atoms in cavity QED.The proposed quantum dialogue protocol avoided the information leakage problem by using the measurement correlation property after entanglement swapping between two Bell states via cavity QED,and could securely exchange 4 bits secret messages per round communication.The results show that the proposed protocol is able to detect the active attacks from the outside eavesdropper through security checking,such as the intercept-resend attack,the measurement-resend attack and the entanglement-and-measurement attack.Therefore,it has good security towards both the information leakage problem and the active attacks from the outside eavesdropper.

QUANTUM DIALOGUE BY USING THE TWO-QUTRIT ENTANGLED STATES

Lingling Zhang, You-Bang Zhan

A protocol for quantum dialogue is proposed to exchange directly the communicators' secret messages by using the two-qutrit entangled state. In this protocol, the security of communication is ensured by the secret transmitting order of qutrits. It is shown that two legitimate users can directly transmit the secret messages by generalized Bell-basis measurement and classical communication.
