Digits Reverse Order Based Approach for Symmetric Encryption/Decryption of Digital Images

Abstract

Information transmission from one point to another point has become play an important role In the new era, where information security is utmost important. Due to having more application of multimedia transfer through wireless communication, art of cryptography provides a security of information which is mathematical algorithm to convert messages into an unreadable form. In this manuscript, an encryption/decryption technique is proposed for color image based on pixel shuffling and Arnold transform. The parameter of Arnold transform utilized during encryption process is considered a secret key for the whole process.

Keywords: Image encryption/ decryption, Symmetric key algorithm, Arnold Cat Transform
