Intuitionistic Fuzzy Soft Set Decision Criterion for Selecting Appropriate Block Cipher

摘要

The primary objective of this work is to put in action a decision making algorithm, based on intuitionistic fuzzy soft set, for making a comparison and selection of the optimally secure S-box, among the several kinds of S-boxes. It is a common fashion to analyze, is to judge quality of S-box by taking into account a single parameter. While we urge to making assessment, about the quality of S-box, by taking into consideration the all parameters collectively, this indeed provides a comprehensive conclusion about the strength of S-box. Moreover, the algorithm also grades the S-boxes on the basis of their strength, and hence process of choosing the secure S-box becomes easier. The proposed method extensively reduces the chances of for piracy in image transmission.
