A Novel Image Encryption Algorithm Based on DNA Subsequence Operation
We present a novel image encryption algorithm based on DNA subsequence operation. Different from the traditional DNA encryption methods, our algorithm does not use complex biological operation but just uses the idea of DNA subsequence operations (such as elongation operation, truncation operation, deletion operation, etc.) combining with the logistic chaotic map to scramble the location and the...
متن کاملA 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 ...
متن کاملA RGB image encryption algorithm based on DNA sequence operation and hyper-chaotic system
The proposed encryption algorithm is composed of two parts, permutation and diffusion. we firstly separate the RGB image into R, G, B components, and Generate three chaotic sequences by chaotic maps to encryption. Then, transform the R, G, B components and the chaotic sequences into DNA code, and get DNA sequences matrix. Secondly, DNA matrices of the RGB image is permutated under the Chen’s hy...
متن کاملA New Image Encryption Algorithm based on DNA Approach
In recent years, various DNA based cryptographic algorithms have been suggested to develop secure image encryption techniques but still many of them have low computing security as they have low avalanche effect and require to send long key . In this regard, this paper proposes a new method of image encryption based on DNA computation technology. The original image is encrypted using DNA computa...
متن کاملA Novel Color Image Encryption Algorithm Based on Chaotic Maps
Due to the character of higher security of three-dimensional chaotic systems, a new algorithm based on Chen and Lorenz systems is proposed to encrypt color images. In order to increase the security of the cryptosystem, the algorithm firstly integrates image information into the Lorenz map, and then the image information is also mixed into the Chen map via the Lorenz map. Theoretical analysis an...
