Abstract

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.

Information Leakage Prevention in Quantum Dialogue Using the Measurement Correlation after Entanglement Swapping and Decreasing the Transmission Efficiency

YE Tian-y

In order to solve the security threat of information leakage in quantum dialogue protocols,a controlled quantum dialogue protocol without information leakage was proposed,where the controller Alice controlled the bidirectional communication between two communication parties,Bob and Charlie.The problem of information leakage was avoided by making full use of the measurement correlation property after entanglement swapping between two maximally entangled GHZ states and decreasing the transmission efficiency.Moreover,the Bell-basis measurement rather than the GHZ-basis measurement was needed.Security analysis shows that the active attacks from an outside eavesdropper can be detected,such as the intercept-resend attack,the measurement-resend attack and the entanglement-and-measurement attack.

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.

Quantum dialogue without information leakage based on the entanglement swapping between any two Bell states and the shared secret Bell state

Tian-Yu Ye, Li-zhen Jiang

In order to avoid the risk of information leakage during the information mutual transmission between two authorized participants, i.e. Alice and Bob, a quantum dialogue protocol based on the entanglement swapping between any two Bell states and the shared secret Bell state is proposed. The proposed protocol integrates the ideas of block transmission, two-step transmission and unitary operation encoding together using the Bell states as the information carriers. Besides the entanglement swapping between any two Bell states, a shared secret Bell state is also used to overcome the information leakage problem, which not only makes Bob aware of the prepared initial state but also is used for Bob's encoding and entanglement swapping. Security analysis shows that the proposed protocol can resist the general active attacks from an outside eavesdropper Eve. Moreover, the relation between the maximal amount of information Eve can gain and the detection probability is derived.

Information leakage resistant quantum dialogue based on Grover’s quantum searching

Q. Chen, Xia Li, Tian-Yu Ye

Abstract This paper proposes a novel information leakage resistant quantum dialogue protocol based on Grover’s quantum searching. This protocol prevents the information leakage problem by directly transmitting the auxiliary two-particle product states from one user to another user. Security analysis proves that this protocol is able to defeat the intercept-resend attack, the measure-resend attack, the entangle-measure attack and the Trojan horse attack from an outside eavesdropper. The qubit efficiency of this protocol after ignoring the eavesdropping check processes is as high as 2/3. This protocol only employs two-particle product states as initial quantum resource, only needs single-particle measurements and does not need to implement quantum entanglement swapping.

Quantum steganography in cavity QED based on the entanglement swapping of any two Bell states

YE Tian-y

In this paper,a novel quantum steganography protocol via cavity quantum electrodynamics(QED)is proposed by using the evolution law of atom in cavity QED,whose hidden capacity is as high as four bits.The proposed protocol builds up a hidden channel to transmit secret messages through the entanglement swapping of any two Bell states in cavity QED.The proposed protocol not only needs no multiparticle quantum entangled state as the quantum resource,but also involves no entanglement swapping or quantum measurement about multiparticle quantum entangled state.Analysis shows that the proposed protocol is able to resist the intercept-resend attack,the measure-resend attack and the entanglemeasure attack,so it has good security.

Authenticated Quantum Dialogue Without Information Leakage

He Wang, Yuqing Zhang, Gaofei Wu +1 more

A lot of authenticated quantum dialogue protocols are springing up. Many of them have the problem of information leakage, or suffer from Man-In-The-Middle attack. Some protocols can guarantee security, but have relatively low efficiency. Based on the above situation, we present a novel authenticated quantum dialogue protocol by using Bell states and entanglement swapping. In this protocol, we adopt Einstein-Podolsky-Rosen (EPR) pairs to detect eavesdropping and transmit secret messages. We employ polarized photons to achieve authentication of users' identity information. Compared with other quantum dialogue schemes with authentication, our protocol has several advantages. The transmitted particles are passed once and do not carry any secret messages. The proposed protocol can overcome the drawback of information leakage and resist against typical attacks. The efficiency is acceptable.
