| 摘 要： | 从密钥管理的“阈值方案”出发，讨论了其“对偶问题”的解决方法，并且将该方法进一步推广，提出了密钥层次推导算法。分析了算法的保密强度及某些参数对保密强度的影响，并讨论了实现此算法的某些关键问题。

| Abstract: | Starting from the threshold value scheme of secret-key management,themethods for solving dual problem have been discussed.As a further extension,a derivationalgorithm of secret-key grading is presented and the cryptograph strength and its influentialparameters,as well as a few key problems to realize this algorithm are also analysed. |
