提出了一个密钥空间为有限域
GF(q)的安全的矢量空间秘密共享方案
该方案能更有效地防止欺诈
欺诈成功的概率仅为1/q
2
信息率是渐进最优的
其值为1/3.同时对鲁棒的门限方案进行了探讨
得出了其欺诈成功的概率最大值的解析表达式.
A secure vector space secret sharing scheme with the secret k∈GF(q)
is presented.This scheme can detect the cheaters more effectively
with the probability of cheating 1/
q
and asymptotically optimal information rate 1/3.Meanwhile
a robust threshold scheme is studied and the expression of its probability of cheating is given.
