摘要
分布式乘法计算协议是应用很广泛的基础密码协议 .分布式乘法计算是构造门限密码体制的基本模块 ,同时也是安全多方计算领域的重要研究内容 .文中分析了几种主要的分布式乘法计算方案 ,并基于可验证秘密共享 ,给出了在不同情况下的多项相乘的鲁棒分布式乘法计算协议 .其中并行不交互的鲁棒分布式多项相乘乘法计算协议效率较高 。
Distributed multiplication computation protocols are widely used as basic cryptographic protocols. They are basic modules to construct threshold cryptosystems, and also important components of secure multiparty computation. Several important distributed multiplication schemes are analyzed in this paper, and based on verifiable secret sharing, some robust distributed multiple multiplication protocols are presented, one of which, the parallelizable non interactive protocol, is more efficient, and has the property of non interaction.
