A new fractional one dimensional chaotic map and its application in high-speed image encryption

Recently proposed ciphers have good performance for sharing low-quality images (256×256) but struggle sharing high-quality images such as Full Ultra HD (7680×4320×3) in real-time.

“Recently proposed ciphers such as [7, 21, 41] have good performance for sharing low-quality images, with dimensions of 256 × 256, but struggle sharing highquality images, such as Full Ultra HD, with dimensions of 7680 × 4320 × 3, in real-time.”

Chaotic encryption schemes perform well for low-quality images but are not fast enough for real-time encryption of Full Ultra HD images.

“Chaotic encryption schemes perform well for low-quality images, however, they are not fast enough for real-time encryption of Full Ultra HD images.”

In image encryption, there are drawbacks considering features of images such as redundancy, similarity of adjacent pixels, and large file sizes.

“In the context of image encryption, there are drawbacks considering features of images such as redundancy, similarity of adjacent pixels, along with large file sizes [7, 41].”

In older works, permutation and diffusion are done separately, but in more recent works they have been implemented simultaneously, reducing the amount of scannings of the plain image.

“In all of the older works in literature the permutation and the diffusion are done separately but in more recent works they have been implemented simultaneously, thus reducing the amount of scannings of the plain image [41, 44].”
