Abstract

我们基于可重用的纠缠的状态为 QKD 介绍一个协议。在这个协议， EPR 作为一把量钥匙配对行为编码并且译码信息粒子。并且一个仅仅信息粒子在给合法地位的用户之间旅行。这改进通讯的安全和效率。另外，我们证明它对一个新 QSS 协议的扩展也安全、有效。

基于纠纷交换，一个量钥匙分发(QKD ) 计划被建议。在这个计划，秘密钥匙被比较起始的贝尔状态和纠纷交换的结果形成。而且，艾莉斯和鲍勃准备的所有起始的贝尔状态是完全任意的。作为在二个聚会之间交换的古典信息很小，这个 QKD 计划有高效率。另外，以便阻止偷听，圈套粒子被使用。

Secure Communication Based on Quantum Key

Song Jie, Yan Xia, He‐Shan Song

We introduce a protocol for QKD based on reusable entangled states. In this protocol, the EPR pairs act as a quantum key to encode and decode information particles. And only an information particle travels between the legitimated users. This improves the security and efficiency of communication. In addition, we show that its extension to a new QSS protocol is also secure and efficient.

Fundamental Two-Party Quantum Secret Sharing Protocol without Quantum Entanglement

Jun‐Cheol Jeon

Quantum key distribution (QKD) protocol techniques are used in the distribution of keys using the laws of physics.Quantum secret sharing (QSS), quantum secure direct communication, and quantum teleportation, which are all included under QKD, are used to share or distribute a secure key in a quantum environment.In QSS, we share a key based on the quantum properties of light.We emphasize cooperation between communicating parties to eliminate untrustworthy members and to improve the strength of the key.The results obtained showed that using the proposed method, it is difficult for eavesdroppers to obtain the key.
