摘要：

Drawing idea from the quantum secure direct communication (QSDC) and the dense coding, we propose a novel quantum secret sharing (QSS) scheme with high efficiency based on the GHZ states. Alice shares her secret message with Bob and Charlie directly using quantum correlations and a public string K, rather than shares a joint key with them and uses the joint key to transmit her message. In our scheme, a GHZ state can be used to share two bits message. We analyze the security of our scheme in the realistic and lossy channel respectively, and show it is necessary to use a public K due to the difference between quantum direct secret sharing and QSDC.
