摘要: 在秘密共享案中,一般集中于(n,t)门限秘密共享方案的研究。文中给出的是具有特殊权限的参与者权重不同的(m+n1+n2+…+nl,t+1+1+…+1)门限秘密共享方案和(m+n1+…+nl,t+t1+…+tl)门限秘密共享方案,它们是(m+n,t+1)门限秘密共享方案的推广形式。基于中国剩余定理分别给出具有特殊权限的且参与者具有不同权重的(m+n1+n2+…+nl,t+1+1+…+1)门限秘密共享方案和(m+n1+…+nl,t+t1+…+tl)门限秘密共享方案。

Abstract: Generally,we just research on (n,t) threshold secret sharing scheme.In this article,we will show (m+n1+n2+…+nl,t+1+1+…+1)and (m+n1+…+nl,t+t1+…+tl) threshold secret sharing scheme among weighted participants of special access right,which is an generalized scheme of (m+n,t+1)threshold secret sharing,and we will give (m+n1+n2+…+nl,t+1+1+…+1)and (m+n1+…+nl,t+t1+…+tl) threshold secret sharing schemes among weighted participants based on CRT of special access right.
