【摘要】The rapid development of information science and technology has brought us into the information age.In the information age,information that exists in the form of data has become an important

strategic

resource

and

digital

wealth.Different

organizations,institutions,enterprises and persons own different private data.The data has great importance for scientific research, business,human health,personal service,social management etc.To make full use of the data, it is necessary for different parties to cooperatively perform some computation on their private data,but this will pose great challenge to the privacy-preserving of the private data.Secure multiparty computation which was introduced in 1980s is a core technology to protect the privacy in both cooperative computation and network world.It has been applied to electronic commerce, secure electronic voting,private data mining,privacy preserving statistical analysis etc.It is also a research focus in the international cryptographic community in recent years.Cryptographic scholars have studied many secure multiparty computation problems such as secure scientific computation,secure data mining,secure computational geometry,secure
