Abstract EN
A robust gray image encryption scheme using chaotic logistic map and artificial neural network (ANN) is introduced.
In the proposed method, an external secret key is used to derive the initial conditions for the logistic chaotic maps which are employed to generate weights and biases matrices of the multilayer perceptron (MLP).
During the learning process with the backpropagation algorithm, ANN determines the weight matrix of the connections.
The plain image is divided into four subimages which are used for the first diffusion stage.
The subimages obtained previously are divided into the square subimage blocks.
In the next stage, different initial conditions are employed to generate a key stream which will be used for permutation and diffusion of the subimage blocks.
Some security analyses such as entropy analysis, statistical analysis, and key sensitivity analysis are given to demonstrate the key space of the proposed algorithm which is large enough to make brute force attacks infeasible.
Computing validation using experimental data with several gray images has been carried out with detailed numerical analysis, in order to validate the high security of the proposed encryption scheme.
