摘要
为了提高量子直接通信的光子利用率和通信效率,基于算术编码提出了一个确定性安全量子通信方案。首先利用喷泉码预先共享少量经典信息,完成测量基信息和解码信息的共享。然后通过简化的算术编码来编码机密信息并制备对应的单光子序列进行机密信息的传输,算数编码的使用提高了协议通信效率和光子利用率。使用与BB84协议同样的物理设备可实现该方案。通过安全性分析可知:该方案具有较高的安全性,可抵抗现有的截取-测量-重放攻击、假信号攻击、纠缠附加粒子攻击和光子数分离等攻击手段。
In order to improve the photon utilization and communication efficiency of quantum direct communication, a deterministic secure quantum communication scheme based on arithmetic coding is proposed. Firstly, the fountain code is used to pre-share a small amount of classical information to complete the sharing of measurement base information and decoding information. Then, the secret information is encoded by simplified arithmetic coding, and the corresponding photons sequence are prepared to transmit the secret information. The using of arithmetic coding improves protocol communication efficiency and photon utilization. What's more, the scheme can be implemented using the same physical device as the BB84 protocol. According to the security analysis, the scheme has high security. It can resist the existing intercept-measure-resend attack, false-signal attack, entanglement-measure attack, photon-number-splitting attack, and so on.
