A Novel Approach for Image Encryption by New M Box Encryption Algorithm using Block based Transformation along with Shuffle Operation

Abstract

In the present brutal competitive world, security is prime factor to transmit confidential data over the internet. Cryptographic algorithms play very important role in providing the data security against the various attacks. The specific characteristics of image, like high transmission rate with limited bandwidth, correlation among pixels, redundancy and requirement of high storage capacity makes traditional algorithms unsuitable for image encryption. To cross these boundaries for real time applications, design of new algorithms that require less computational power while preserving a sufficient level of security is always a big challenge for researchers. This paper proposes an algorithm based on block based image transformation using perfect shuffle operation followed by new encryption algorithm. In this paper we compare the generated results with available algorithms like AES, RC6 and BFS on the basis of two parameters entropy and correlation.

Solving security issues in mobile computing using cryptography techniques — A Survey

“…It is called symmetric key cryptography. [10]. Some commonly used algorithms are-AES, DES, IDEA, RC2, BLOWFISH.…”

“…A public key is used to encrypt the message at sender's end and a private key is used to decrypt the message at receiver's end. For the same message, two different keys will generate two different cipher texts [10]. It is called asymmetric key cryptography.…”

“…Due to the small key size of 56-bits, DES is now considered to be unsafe and insecure from point of view of many applications. [10] It suffers from the problem of Simple Relations in its keys due to complementary relations between keys resulting in a complementary relationship between the resulting cipher text. [9] The DES algorithm is susceptible to Linear Cryptanalysis attacks.…”

“…is the estimation of mathematical expectations of x, and D(x) is the estimation of variance of x, and also Cov(x,y) is the estimation of covariance between x and y. In addition, x and y are grey scale values of two adjacent pixels in the image [30,33]. that w and h are the width and height of or .…”
