The main contribution is to design a cryptographically keyed strong S-Box construction method, based on a non-degenerate 3D improved quadratic map (3D-IQM). First, a 3D-IQM is constructed, dynamics analysis demonstrated its ergodicity and better randomness in phase space. Based on 3D-IQM, a keyed dy...
