A 4D hyperchaotic image encryption scheme using Circular Radius–Angle Transformation and bit-level permutation
With the rapid growth of digital data transmission, secure image encryption has become a critical requirement for protecting visual information against unauthorized access and cryptanalytic attacks. Existing chaotic-based encryption schemes often suffer from limited resistance to statistical and differential attacks du...
