A quantum secret sharing scheme with two-way authentication was proposed and discussed. Based on two-particle quantum entanglement, the scheme is implemented using the Hash function and the quantum local operations. The authentication keys and the secret order of transmitted particles ensure the security of the scheme. One Bell state can be used to share two classical bits on average if the particles for authentication and eavesdropping detection are not concernred.
