Abstract: This paper presents an efficient image encryption scheme that uses a 3D logistic map, SHA-512, and pixel scrambling techniques. Firstly, two secret keys are generated using two different user-provided keys and the input image. Image pixels are altered using the values obtained upon the iteration of the 3D logistic map to increase the complexity of the algorithm. Further, different fragments of various sizes are swapped depending on the secret keys. Finally, a jumbling technique mixes the pixels horizontally and vertically in a completely dynamic way using secret keys. The keyspace of the algorithm is large enough to resist brute force attacks. The encrypted image has been analysed against classical attacks such as chosen-plaintext, chosen-ciphertext, known-ciphertext, known-plaintext, and statistical attacks. Key sensitivity analysis and noise resistance analysis have also been performed. The results prove that the algorithm is resistant to several renowned attacks, enabling usage in various real-time applications.
