Chain of Shuffling and Chaos: A Tied Encryptic Approach

Abstract

The intellectual growth of computer communication lead to drastic improvement in wireless technology and shrunken the world into palms of the user which paved the path for the security attack issues. The development of the security system became the ultimate. Popular technique widely used in present scenario that provides a better security to secret information is image encryption. Multiple encryption technique has been adopted in this study. The secret image is block shuffled and then chaotic maps such as baker map, skew tent map and Arnold cat map are used to encrypt the image. Further the image is encrypted using Cipher Block Chaining (CBC) to contribute the final encrypted image. Metrics such as horizontal, vertical, diagonal correlation, Number of Changing Pixel Rate (NPCR) and entropy were calculated for various Digital Imaging and Communication in Medicine (DICOM) test images and the performance of the algorithm was analyzed.

Chaotic & partial encrypted image on XOR bus - an unidentified carrier approach

“…In this modern world, digital communication has wide range of applications for information security which could be classified as Steganography [5][6][7][8][9][10][11][12][13][14][15][16][17], Watermarking [2,6], Spread Spectrum [18][19][20][21][22] and Encryption [23][24][25][26][27][28][29][30][31][32][33][34][35].…”

“…Hence various techniques have been introduced to maintain the secrecy of the information transferred. The most popular technique thus used is image encryption [23][24][25][26][27][28][29][30][31][32][33][34][35].…”

“…Encryption is the process of altering the original information so as to make it unrealizable for the third party [31][32][33][34][35]. The encryption process carries number of stages depending upon the complexity of the encryption algorithm used.…”

Yet another but an incremental reversible data hiding- for an irreversible data safety

“…Information hiding techniques [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] can be classified into reversible [20] and irreversible information hiding [21]. In irreversible technique, extraction of the message alone is concentrated leaving behind the cover.…”

“…Out of the various data hiding schemes, the encryption is the popular technique which is the process of modifying the secret data in such a manner that no one could read the data before decryption [17][18][19].…”
