摘　　要：互联网、大数据的快速发展,给人们的日常生活带来了极大的便利,同时也给数据隐私保护等方面提出了更高的要求。作为安全多方计算的重要组成部分,基于秘密共享的洗牌协议可以有效的保护数据隐私,提高网络的安全性,因此得到了广泛的使用。本文综述了基于秘密共享的洗牌协议的种类和功能,将其分为基于公钥密码方式、基于对称密码方式和基于共享转换方式,并分别在应用、效率等方面进行了对比分析。本文还对比了不同洗牌协议的安全性能,得出了采用共享转换方法的洗牌协议具有更好的安全性的结论。最后,本文结合了当下的热门研究类型,从参与者的增加、协议的优化,协议的有机结合等方法对该协议提出了优化方向。Rapid development of the internet and big data brings great convenience to daily life,mean-while putting forward higher requirements for data privacy protection and other aspects.As an important component of the secure multiparty computing,shuffling protocol based on secret sharing could effec-tively protect the data privacy and improve the network security,hence widely used.In this paper,types and functions of reshuffling protocols based on secret sharing are summarized,which are classified into public key cryptography based,symmetric cryptography based and sharing conversion based.Appli-cations and efficiency of the three types are compared and analyzed respectively.Security performance comparison indicates that the sharing conversion based shuffling protocols achieve higher security.Final-ly,combining with the current popular research,we present optimization directions of the protocol from aspects of increasing the participants,optimizing the protocol,and combining the protocol with other methods.
