| 摘 要： | 为使攻击者在骗取所有共享者的子秘密时无法恢复秘密，提出一种基于密钥协商的门限多秘密共享方案。该方案使系统内的成员相互制约，子秘密由共享者自己选取，且可重复使用，系统不需要秘密信道。共享者可以方便地动态加入或离开系统，且所有秘密能一次性恢复。

| Abstract: | This paper proposes a threshold multi-secret sharing scheme based on key agreement to assure that secret data can not restored by attackers have diddled subsecrets from all the participants. The cheating of dealer and the cheating of participants can be detected. The subsecrets are chosen by the participants themselves and can be used repeatedly. System does not need a security channel. It is easy for the participants to join or leave system dynamically, and all the secrets can be recovered in one time. |
