摘要
本文通过对密钥共享体制安全性的完整刻画,讲述了完美的、统计的和计算的三大类密钥共享体制的统一定义。进而,分析了具有乘性的线性密钥共享体制为何和如何用于安全多方计算,同时较详细地分析了安全多方计算的安全性含义。
In the paper, through a complete description of secret sharing schemes, we give definitions respectively for perfect secret sharing schemes, statistical secret sharing schemes and computational secret sharing schemes in an uniform way. Furthermore, we analyze why and how mulfiphcative linear secret sharing schemes are used in secure multi-party computation protocols, and explain the security of secure multi-party computation in detail.
