Detector-device-independent quantum secret sharing based on Bell-state distribution
Imperfect single-photon detectors can lead to security flaws such as key information leakage and malicious information injection.We propose a three-party detector-device-independent quantum secret sharing protocol based on the single-photon Bell-state measurement and two-photon Bell-state distribution.Two agents develop connections among three communication parties by implementing spatial encoding of photons and performing single-photon Bell-state measurements in both polarization and spatial mode degrees of freedom,resulting in secret sharing among the three parties.This protocol can be implemented with linear optical elements and is simple for practical applications.Furthermore,we prove the security of the protocol and demonstrate its resistance to two common eavesdropping attacks.
