【摘要】 文章提出了一种基于单向函数的动态秘密分享方案，它可以无限次地更新秘密，而成员所拥有的分享值却无须改变，还可以检测出不诚实的成员，并且所需的存储量和计算量都比Sun－Shieh[7]方案有了降低。更多还原

【Abstract】 In this paper, we propose a new (t,n) dynamic secret scheme based on one-way function. It allows the shared secret to be renewed infinitely without changing the shares of the participants. It is also able to detect the cheaters. Compared with Sun-Shieh scheme[1], the number of public values of it is reduced and the amount of computation is decreased.更多还原
