A Secure and Efficient Image Encryption Algorithm Based on DNA Coding and Spatiotemporal Chaos
In this paper, an image encryption algorithm based on DNA random coding and random operation combined with chaotic map is proposed. In order to produce sequences with more chaotic characteristics, a new spatiotemporal chaotic system is proposed by employing the Tent-Sine system (TSS) in the coupled map lattice (CML). SHA-256 hash of the plain image is used to generate secret keys. The Lorenz Ma...
متن کاملChaotic Image Encryption Algorithm Based on Bit Permutation and Dynamic DNA Encoding
With the help of the fact that chaos is sensitive to initial conditions and pseudorandomness, combined with the spatial configurations in the DNA molecule's inherent and unique information processing ability, a novel image encryption algorithm based on bit permutation and dynamic DNA encoding is proposed here. The algorithm first uses Keccak to calculate the hash value for a given DNA sequence ...
متن کاملA 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 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 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 ...
