Evaluation of the cryptographic algorithmic proposal with the incorporation of steganography into images

Abstract:

The present study was quasi experimental, applicative and integrated two fields of security: the cryptography that encrypts the message and the steganography that hides the message behind a multimedia medium, which strengthens the level of security. Netbeans was the software used for the research as a development environment, Beyond Compare to compare the hexadecimal code of the images, Ion Forge Image Diff to compare the differences between pixel to pixel images and Cyptool for the cryptanalysis tests. The AES (Advanced Encryption Standard) cryptographic algorithm was used as the basis and LSB (Least Significant Bit) was selected for the steganographic technique in images. New functions that were included in Prototype II were implemented and evaluated, and results obtained by running cryptanalysis were compared to the encrypted messages between Prototype II, that uses the new …
