Multi-party Quantum Secure Direct Communication

Xiaoqing Tan, Xiaoqian Zhang, Cui Liang

A protocol for three-party quantum secure direct communication using entanglement states is proposed. In this protocol, three participants simultaneously exchange their messages. The protocol is shown to stand against the intercept-and-resend attack, the intercept-and-measure attack, the intercept-and-entangle auxiliary attack and the denial-of-service attack. It can be generalized to N-party case that is feasible.

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.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.
