With the help of quantum computation operator, a quantum secret sharing scheme based on polarized single photons is proposed. Efficiency analysis indicates that all qubits can be used in the secret sharing. With the permutation operator and quantum entanglement, the protocol can resist the middleman attack effectively. By using the auxiliary qubit, the protocol can detect the Trojan horse attack with high probability. The extension of the permutation operator shows the scheme which contains n pairs is feasible and applicable.
