A New Fast Data Encryption Algorithm (FDE)

A Novel Image Encryption Model Based on Hybridization of Genetic Algorithm, Chaos Theory and Lattice Map

Encryption is an important issue in information security which is usually provided using a reversible mathematical model. Digital image as a most frequently used digital product needs special encryption algorithms. This paper presents a new encryption algorithm high security for digital gray images using genetic algorithm and Lattice Map function. At the first the initial value of Logistic Map ...

A new encryption algorithm for image cryptosystems

There are two major di€erences of the characteristics of the text data and image data. One di€erence is that the size of image data is usually much larger than that of text data. The other is that plain data rarely permit loss when a compression technique is used, but image data do. In this paper, we design an ecient cryptosystem for images. Our method is based on vector quantization, which is...

A Self-Adaptive Algorithm on Image Encryption

Abstract: In this paper, a new self-adaptive image encryption algorithm is presented, which takes on a thorough integrity protect function and can be used in data validation. First, ergodic matrices are used to realize the position permutation algorithms. In particular, several novel methods of scrambling are proposed. By analysis of the weakness of pure position algorithms, a novel improved se...

A New Chaos-Based Image Encryption Algorithm

In this paper, we propose a new image encryption algorithm based on the Compound chaotic image encryption algorithm. The original one can’t resist chosen-plaintext attack and has weak statistical security, but our new algorithm can resist the chosen-plaintext attack using a simple improvement solution. The improvement solution is novel and transplantable, it can also be used to enhance the abil...
