Abstract: In secret sharing,generally,we just research on(n,t) secret sharing scheme.Based on special access right(m+n,t+1)threshold secret sharing is an generalized scheme of(n,t) secret sharing,and we will give another(m+n,t+1) threshold secret sharing scheme based on Shamir scheme under special access right.

Key words: secret sharing scheme, special access right, threshold secret sharing

摘要: 在秘密共享方案中,一般研究(n,t)门限秘密共享方案。具有特殊权限的(m+n,t+1)门限秘密共享方案是(n,t)门限秘密共享方案推广形式的门限秘密共享方案。在差分门限秘密共享方案的基础上构造基于Shamir方案,给出了(m+n,t+1)门限秘密共享的另一方案。
