摘要
安全多方计算、全同态加密和零知识证明是解决数据安全问题的重要密码技术,其快速发展和应用需求驱动,引发了新形态对称密码的设计与安全性分析.本文系统介绍适宜安全多方计算、全同态加密和零知识证明的新形态对称密码算法.首先梳理新形态对称密码算法的应用需求和设计目标;然后归类介绍新形态对称密码算法的设计理念和最新的安全性评估结果;最后总结探讨新形态对称密码算法的设计特点以及面临的问题.
Abstract
Secure multi-party computation,fully homomorphic encryption,and zero-knowledge proof are important cryptographic techniques to solve data security problems.Their rapid develop-ment and application demand drive the design and security analysis of new morphologic symmetric cryptography.In this paper,new morphologic symmetric cryptographic algorithms suitable for secure multi-party computation,fully homomorphic encryption,and zero-knowledge proof are systematically introduced.Firstly,the application requirements and design principles of the new morphologic sym-metric cryptographic algorithms are reviewed.Then the design principle of the new morphologic symmetric cryptographic algorithms are introduced in different categories,and the latest security eval-uation results are analyzed.Finally,the design features and the existing problems of new morphologic symmetric cryptographic algorithms are discussed.
