Abstract:

This report summarizes the existing typical cryptographic structures, such as Feistel structure, Lai-Massey structure, and SPN structure, etc., and proposes a classification standard for cryptographic structures in order to unify Feistel structure and Lai-Massey structure. On this basis, the report gives a batch of cryptographic structures with similar encryption and decryption.
