As remote sensing images are widely used, their security has also received extensive attention. This paper proposes a novel remote sensing image encryption algorithm (RSIEA) using the designed one-dimensional (1D) chaos and differential coding. Firstly, the pixels in the plain image are permuted using the index sequence of chaotic sequence. Secondly, we design a differential coding scheme, which can permute and diffuse the image at the same time. Finally, chaotic image and XOR operation are used together to further enhance the diffusion effect. Experiment results and security analyses demonstrate the high security of our algorithm. In other words, our algorithm can guarantee the secure transmission and storage of remote sensing images.
