In the traditional Chord-based botnets, all adjacent nodes need to maintain the periodic communication so that the routing table of every node keeps accurate and efficient. The periodic communication behavior affects the robustness of the traditional Chord-based botnets. For the aforementioned problems, a Chord-based quantum botnet control platform based on the improved B92 protocol was constructed. The simulation analysis showed that the infected hosts in the Chord-based quantum botnet can more quickly be increased, and can maintain a larger scale compared with the traditional Chord-based botnet. Meanwhile, the Chord-based quantum botnet can reduce the hazards of the periodic communication behavior on botnet control system and has better robustness and stability.
