安全多方计算的应用研究

安全多方计算(SMC)在解决网络环境下进行合作时的信息安全问题具有重要价值。笔者首先介绍了安全多方计算的基本概念、密码学中相关基础知识,接着介绍和分析了安全多方计算的在电子选举、电子签名和门限签名等方面的基本应用;在该基础上,指出安全多方计算的新的应用方向,即在机械设计工程领域中的应用,如产品的异地设计和制造、敏捷和虚拟制造技术等;提出了值得进一步研究和探讨的、在保护隐私基础上合作的安全多方计算的热点问题。

Application Research of Secure Multi-party Computation

Secure multi-party computation (SMC) plays an important role in information security under the circumstance of network cooperation. The paper firstly introduces the basic concept of SMC and related knowledge of cryptology, and then illustrates its application in electronic vote, electronic signature and threshold signature. Based on this, a new application direction in mechanical engineering design, such as product designing and manufacturing in other places, flexible and virtual manufacture techniques and so on is put forward. Finally, some worth-researching hot questions about cooperative SMC on the condition of privacy protection are presented.
