| 摘 要： | 提出了一种新的基于椭圆曲线密码体制的(k,n)多秘密共享方案。该方案具有以下特点:参与者能自主选择子秘密;在进行一次秘密恢复后,不会泄露关于子秘密的任何信息,子秘密仍可用于下一个秘密的恢复;参与者的子秘密可定期更新,且更新工作由每个参与者独立完成。与传统的多秘密共享方案相比,该方案具有更高的安全性和灵活性。

| Abstract: | A new(k,n)multi-secret sharing scheme based on the ECC is proposed.The scheme has properties as follows: participants can choose sub-secrets by themselves;the information of sub-secrets can not be leaked while a secret is recovered,and another secret can be recovered by the same sub-secrets;sub-secrets of participants can be renewed periodically,which is completed by participants themselves.So this scheme has higher security and better flexibility. |
