| 摘 要： | 现有的门限多秘密共享方案中，大多数存在着固定的门限值、多次利用单秘密共享来实现多秘密共享等问题。为了解决这些问题，文中提出了一种动态（t，n）门限的多级多秘密共享方案。此方案具有如下特点：对于不同等级的多秘密，多秘密分发者可动态地调整其恢复时的门限值；对于相同等级的多秘密，多秘密分发者在分发、恢复、更新和验证等操作时能一次完成。 |
| 关 键 词： | 多秘密共享 离散对数 动态门限 |

| Abstract: | In the most present threshold multisecret sharing scheme exist some problems, such as fixed threshold, multisecret sharing realization by using single secret sharing many times. To overcome these problems,a dynamic（t, n） threshold multilevel multisecret sharing scheme is proposed in this paper, This scheme has the following properties： as for the multisecret of the different grade, the multisecret distributer could dynamically adjust the threshold value; as for the multisecret of the same grade the distributer could accomplish at one time the operations such as distribution, recovery, updating and authentication. |
| Keywords: | secret sharing discrete logarithm dynamic threshold |
