摘要
作为一种新兴的光通信物理层安全技术,量子噪声流加密结合了数学复杂度和物理复杂度,具有高安全、高速率、长跨距、结构灵活、与现有光纤通信系统高度兼容等优点。详细阐述量子噪声流加密的研究现状和基本原理,在密钥协商方面,对比了量子噪声流加密的Y-00协议与量子密钥分发的BB84类型协议,概述量子噪声流加密的关键技术方案。介绍了量子噪声流加密的典型应用案例,提出一种统一协商信道和传输信道的内生安全光通信系统,并进行了实验验证。最后分析量子噪声流加密的发展趋势。
As a new security technology in the physical layer of optical communication,quantum noise stream cipher combines mathematical complexity and physical complexity.The quantum noise stream cipher has the advantages of high security,high speed,long span,flexible structure,and high compatibility with the existing optical fiber communication systems.This paper presents the current research status and the basic principle of the quantum noise stream cipher.In the aspect of key negotiation,we compare the Y-00 protocol of quantum noise stream cipher with the BB84-type protocol of quantum key distribution and summarize the quantum noise stream cipher’s key technical schemes.Additionally,we introduce a typical application of quantum noise stream cipher and propose an endogenously secure optical communication system with a unified negotiation channel and transmission channel.The experimental verification is demonstrated,and finally,the development trend of a quantum noise stream cipher is analyzed.
