Breaking a chaotic image encryption algorithm based on modulo addition and XOR operation

چکیده
This paper re-evaluates the security of a chaotic image encryption algorithm called 13 MCKBA/HCKBA and finds that it can be broken efficiently with two known plain-images and 14 the corresponding cipher-images. In addition, it is reported that a previously proposed breaking 15 on MCKBA/HCKBA can be further improved by reducing the number of chosen plain-images 16 to two from four. The two attacks are both based on some properties of solving a composite 17 function involving carry bit, which is composed of modulo addition and bitwise OR operations. 18 Both rigorous theoretical analysis and detailed experimental results are provided to support the 19 found points. 20

A stack-based chaotic algorithm for encryption of colored images
In this paper, a new method is presented for encryption of colored images. This method is based on using stack data structure and chaos which make the image encryption algorithm more efficient and robust. In the proposed algorithm, a series of data whose range is between 0 and 3 is generated using chaotic logistic system. Then, the original image is divided into four subimages, and these four i...
متن کاملImage encryption based on chaotic tent map in time and frequency domains
The present paper is aimed at introducing a new algorithm for image encryption using chaotic tent maps and the desired key image. This algorithm consists of two parts, the first of which works in the frequency domain and the second, in the time domain. In the frequency domain, a desired key image is used, and a random number is generated, using the chaotic tent map, in order to change the phase...
متن کاملMultilevel Image Encryption
With the fast evolution of digital data exchange and increased usage of multi media images, it is essential to protect the confidential image data from unauthorized access. In natural images the values and position of the neighbouring pixels are strongly correlated. The method proposed in this paper, breaks this correlation increasing entropy of the position and entropy of pixel values using bl...
متن کاملA New Method for Encryption of Color Images based on Combination of Chaotic Systems
This paper presents a new method for encryption of color images based on a combination of chaotic systems, which makes the image encryption more efficient and robust. The proposed algorithm generated three series of data, ranged between 0 and 255, using a chaotic Chen system. Another Chen system was then started with different initial values, which were converted to three series of numbers from...
متن کاملBreaking a novel image encryption scheme based on improved hyperchaotic sequences
Recently, a novel image encryption scheme based on improved hyperchaotic sequences was proposed. A pseudorandom number sequence, generated by a hyper-chaos system, is used to determine two involved encryption functions, bitwise exclusive or (XOR) operation and modulo addition. It was reported that the scheme can be broken with some pairs of chosen plain-images and the corresponding cipher-image...
