A new hyperchaotic map and its application in an image encryption scheme

作者：

Highlights：

• We propose a new 2D map derived from the serpentine curve equations.

• We prove that the proposed map is hyper-chaotic.

• We propose a new algorithm for generating random permutations.

• We propose a new image encryption scheme.

• We performed a standard analysis of the performances of the proposed encryption scheme.
