A New Image Encryption Algorithm based on DNA Approach

A 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...

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...

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...

A New Fast Data Encryption Algorithm (FDE)

A new image encryption algorithm based on hyper-chaos

This Letter presents a new image encryption scheme, which employs an image total shuffling matrix to shuffle the positions of image pixels and then uses a hyper-chaotic system to confuse the relationship between the plain-image and the cipher-image. The experimental results demonstrate that the suggested encryption algorithm of image has the advantages of large key space and high security, and ...
