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.
