Abstract: The paper proposes a dynamic threshold multi-secret sharing scheme among weighted participants based on Chinese remainder theorem.Each participant’s secret shadow is selected and kept by the participant himself and the shadows don’t need to change when the shared secret is renewed，and many secrets can be recovered in one time.Dealer can check whether each participant provides the true information，and a participant can be freely accepted or fired，so a secure channel between them is unnecessary.

摘要： 基于中国剩余定理，提出了一个参与者有权重的动态门限多重秘密共享方案。该方案中参与者的子秘密由自己选取和保存，每个参与者的子秘密可以多次使用，并且一次可以恢复多个秘密。在秘密分发和恢复过程中都可验证参与者是否进行了欺诈。该方案可以灵活地增加或删除成员，且不需要安全信道。
