We　present　a　quantum　secret　sharing　protocol　against　collective-amplitude-damping　noise.　Each　logical　qubit　is　encoded　in　two　qubit　noiseless　states.　So　it　can　function　over　such　a　noisy　channel.　The　two　agents　encode　their　messages　on　each　logical　qubit　only　by　performing　a　permutation　operation　on　two　physical　qubits.　Although　each　logical　qubit　received　by　each　agent　only　carries　a　bit　of　information,　the　boss　Alice　can　read　out　her　agents＇　information　by　discriminating　two　orthogonal　states　by　performing　single-qubit　measurements　assisted　by　local　operation　and　classical　communication　(LOCC).
