| 摘 要： | 为了增强Ｓｈａｍｉｒ密钥共享的（ｋ，ｎ）门限方案的安全性，文中基于单向哈希函数介绍了一种简单的欺骗者认定方法。该欺骗者认定方法引入算术编码原理之后不仅能检测出密钥重构过程中的欺骗行为，而且能确定谁是欺骗者。

| Abstract: | Based on one-way hashing function, this paper introduces a simple cheater identification method for enforcing the security of Shamir's secret sharing (k, n) threshold schemes. As arithmetic coding principles being introduced,the cheater identification method not only can detect cheating in the secret reconstructing process,but also can identify the cheaters. |
