A Probabilistic Chaotic Image Encryption Scheme

This paper proposes a probabilistic image encryption scheme that improves on existing deterministic schemes by using chaining mode of chaotic maps in permutation-masking process. Despite its simplicity, the permutation phase destroys any correlation between adjacent pixel values meaningful image. The masking phase, however, modifies at hand pseudorandom numbers with some other initiated random so slight change plain spreads throughout corresponding cipher These ensure generation distinct images for same encryption, even if it is encrypted multiple times key, thereby adding security features. Simulations show proposed robust to common statistical and threats. Furthermore, shown be competitive schemes.
