Query: Quantum secret sharing between multiparty and multiparty with four
  states   An protocol of quantum secret sharing between multiparty and multiparty with
four states is presented. We show that this protocol can make the Trojan horse
attack with a multi-photon signal, the fake-signal attack with EPR pairs, the
attack with single photons, and the attack with invisible photons to be
nullification. In addition, we also give the upper bounds of the average
success probabilities for dishonest agent eavesdropping encryption using the
fake-signal attack with any two-particle entangled states.
