摘要 提出了一个安全的门限秘密共享方案,利用齐次常系数线性差分方程的结构及其解的结构,实现了具有不同访问权限的成员参与的秘密共享,并给出了(m+u,t+1)门限方案的概念. A secure threshold secret sharing scheme is proposed. This scheme realizes secret sharing among the members having difference access right by structures and solution structures of constant coefficients homogeneous linear difference equation. And the concept of (m+ u, t + 1) threshold scheme is defined.
