| 摘 要： | 目前的多等级门限共享方案中，高等级用户的作用可以被若干个低等级用户联合取代，而多秘密门限共享方案中，所有秘密只能在同一级门限下共享。为克服这两个问题，利用Birkhoff插值法和离散对数的困难性，提出了一个可认证的多等级门限多秘密共享方案。该方案可以同时划分多个等级，而每级门限下可以共享多个秘密。每个参与者只需持有一个子秘密，方便管理与使用。 |

| Abstract: | In the current multi-level secret sharing scheme, the presence of higher-level participants could be replaced by several lower-level participants. As to the multi-secret sharing scheme, secrets could only be shared under the same level. To eliminate the two limitations, based on Birkhoff Interpolation and the intractability of discrete logarithm, a new verifiable hierarchical threshold multi-secret sharing scheme was proposed. This scheme simultaneously maintained multiple levels and multiple secrets for every threshold level. Every participant kept one sub-secret only, which was convenient to manage and use. |
| Keywords: | hierarchical multi-secret threshold secret sharing verifiable discrete logarithm |
