A quantum signaling transmission scheme based on quantum entanglement, local umtary operation and teleportation is proposed for signaling transmission in a multiuser quantum signaling network with multi-stage hierarchy level network topology. The analytical result shows that the scheme is secure in case of eavesdropping attack including intercept-measure-resend attacks, intercept-replace and adding-ancilla attacks. Consequently, the probability model of quantum signaling transmission damage probability and the repair strategy of the damage of quantum signaling are presented, and the probability model in noise background and non-ideal traditional channel has very low complexity.
