A DNA-based security solution using aggregated chaos cross and cubic Map

Abstract EN

DNA, cryptography and chaos, can be combined as a whole aggregated DNA, chaos-based and cryptography Discrete Chaotic Cryptography (DCC) to encrypt and decrypt data simultaneously.

A new image encryption scheme based on chaotic system and DNA encoding has been proposed in this paper.

Firstly the image is permuted by mixing the horizontally and vertically adjoint pixels with the help of Cross Chaotic Map (CCM).

Afterwards, the permuted image is divided into Least Significant Bits (LSB) and Most Significant Bits (MSB).

Each LSB and MSB is further divided into two blocks and encoded by DNA sequence.

The encoded blocks are combined and XOR operation is performed to get a diffused image.

Finally the diffused image is permuted by a cubic chaotic map to accomplish the confusion phase and cypher image is obtained.
