Classification of Nonlinear Confusion Component Using Hybrid Multi-Criteria Decision Making

In today’s digital world, the most inevitable challenge is protection of information. Due to weak confidentiality preserving techniques, existing world facing several information breaches. To make our data indecipherable unauthorized person, a technique for finding cryptographically strong Substitution box (S-box) have presented. An S-box with sound cryptographic assets such as nonlinearity (NL), strict avalanche criterion (SAC), bit independence criteria (BIC), (BIC-NL), Bit Strict (BIC-SAC), and Input/output XOR considered robust S-box. The Decision-Making Trial Evaluation Laboratory (DEMATEL) approach multi-criteria decision making (MCDM) proposed interrelation among properties. A combination two MCDM methods namely Entropy multi-objective optimization based on ratio analysis (MOORA) applied best selection. substitution selected secure communications in cryptography by using DEMETAL selection criteria, entropy weight assigning, MOORA ranking scheme. these three provides fast procedure confusion component. offered method can also be utilized choice cryptosystem highly properties resistive against all possible linear differential attacks cryptanalysis.
