Abstract

我们分析量的安全安全直接通讯(QSDC ) 协议并且发现一个偷听者能利用 GHZ 状态的一个特殊性质没有被检测，得到所有播送秘密或部分。特别攻击策略详细被介绍。我们给这个协议的一个改进版本以便它能抵抗这攻击。

We analyse the security of a quantum secure direct communication (QSDC) protocol and find that an eavesdropper can utilize a special property of GHZ states to elicit all or part of the transmitted secrets without being detected. The particular attack strategy is presented in detail. We give an improved version of this protocol so that it can resist this attack.

Efficient One-Sender Versus N -Receiver Quantum Secure Direct Communication

Man Zhong-Xiao, Yun‐Jie Xia

An efficient quantum secure direct communication protocol with one-sender versus N -receiver is proposed. The secret bits can be encoded in the N +1-particle GHZ states and can be decoded by the N receivers with a classical information of the sender plus their own measurement outcomes. Any attacks can be detected by comparing measurement results on the detecting states.

Deterministic Quantum Secure Direct Communication Protocol Based on Omega State

Leilei Li, Jian Li, Chaoyang Li +4 more

A quantum secure direct communication (QSDC) protocol is presented. In the proposed protocol, the omega state is introduced to detect the eavesdropping during the quantum communication, eavesdropping behaviors will change the state of the omega state, and the sender Alice and the receiver Bob detect eavesdropping through the state measurement results. The relationship between the amount of information that the eavesdropper gets and the probability of being detected is also given. Compared with the original QSDC protocol based on the Bell state, when the same amount of information is obtained, the eavesdropper must face a higher detection probability in the proposed protocol, and the eavesdropper mostly can obtain 0.676 (bit) of information. The security analysis is also given, and the result indicates that the proposed protocol is more secure. A simulation based on the law of large number and the Monte Carlo method is also given, and the mean square error is introduced to describe the similarity between the simulation data and the theoretical value. The simulation result indicates that the proposed security in an ideal environment and the security analysis are correct, and the proposed protocol is more secure by sending more quantum particles in detecting eavesdropping.
