Abstract :
A multiparty quantum secret sharing scheme is proposed to utilize the magic properties of entanglement swapping. In this scheme, a set of (2N-1) EPR pairs is used to encode and distribute a secret message to (N-1) parties. Each secret message will be split into (N-1) packets. By performing the local unitary operations and entanglement swapping, each classical bit packet will be encoded secretly into Bell states so no subset of parties but their entire cooperation can read out the original secret message. The security of this proposed scheme is also considered.
