| Abstract: | 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. |
| Keywords: | Multi-user quantum signaling Signaling transfer Security Photon number splitting attack Decoy state |
