An image encryption algorithm with a plaintext?related quantisation scheme

This paper describes an image encryption algorithm that utilises a plaintext-related quantisation scheme. Various approaches from other algorithms are presented and their properties briefly discussed. Main advantage of the proposed solution is achievement similar behaviour like more complex with technique used in rather simple step such as quantisation. design should result favourable computational complexity whole algorithm. The proposal evaluated by number commonly numerical parameters. Also, statistical pseudo-random sequence quantised according to plain pixel intensities investigated tests NIST 800-22 suite. Obtained results compared values reported related works they imply produces encrypted images comparable but authors' faster efficient.
