Image encryption through two rounds of Feistel operating at the bit level

in the present paper, we will introduce a novel color image cipher scheme based on two enhanced rounds of the Feistel network operating at the bit level. This work aim to generate a new method that is fast, secure, and reliable, capable of addressing any known attack. The original image is first converted into binary and divided into several blocks of stochastic size calculated from the utilized chaotic sequences. Simulation results on a sample of images using our technique exhibit the robustness of our system. Notation: $\begin{cases}G_{m}=Z / m Z \text { ring } \\ E(X): \text { Integer part of the float } x\end{cases}$
