摘要： 在模糊保险箱方案中，通常采用多个干扰点与用户特征点混合构成的集合表示保险箱，这种方法存在多种安全缺陷。为此，提出一种新的保险箱构造方案，该方案利用随机点与用户特征集合构造一个随机多项式，运用该多项式系数表示保险箱。分析结果表明，该方案可以抵抗已知的对模糊保险箱的多种攻击，具有更高的安全性，并能节约存储空间。

Abstract: In fuzzy vault scheme, a set with genuine points of a user mixed with a lot of chaff points represents a vault. However, there are some secure flaws in this scheme. To solve these problems, a novel scheme is presented to construct a vault, in which a random polynomial instead of a set is used to represent the vault. Theoretical analysis results show that the new scheme can defeat the existed attacks. It needs less memory than that in the original scheme.
