摘要
本文提出了一个多用户量子信令传输系统,并详细阐述了信令在信道中的传输过程.研究了传输过程中信令受到第三方恶意攻击的损伤模型,并将诱骗态的思想引入量子信令安全的直接通信中,分析了采用不同光强来发送光脉冲,以克服光子数分裂攻击的问题,从而提高了信令传输的安全性.仿真结果表明,本文所提出的对多用户信令攻击的修复策略可有效地检测到光子数分裂数攻击,并增加了安全传输距离,从而保证信令传输过程安全有效的进行.
A quantum signaling transmission system of multi-user is presented,and the transmission process signaling channel is introduced.The damage model maliciously attacked by the third party is analyzed in the transmission process,and the idea of decoy state is introduced to the safety of quantum signaling in direct communication.To overcome photon number splitting(PNS) attack,light pulses are sent using different light intensities,which also improve the safety of the signal transmission.The simulation result shows that repair strategy of multi-user quantum signaling transmission system being attacked can effective detect the PNS attack,and increase distance of security transmission,to ensure the signaling transmission process safely and effectively.
