we　present　a　robust　and　universal　quantum　secret　sharing　protocol　with　four-qubit　decoherence-free　(DF)　states　against　collective　noise.　The　transmission＇s　safety　is　ensured　by　the　nonorthogonality　of　the　noiseless　states　traveling　on　the　quantum　channel.　Although　this　scheme　uses　entangled　states　for　encoding,　only　single-particle　product　measurements　are　required.
