New 2D CA based Image Encryption Scheme and a novel Non-Parametric Test for Pixel Randomness
This work addresses the need for improved randomness testing in image encryption for security applications, but it appears incremental as it builds on existing cellular automata methods.
The paper tackled the problem of validating a new non-parametric test for pixel randomness by designing a 2D cellular automata-based image encryption scheme, and the result was that the encryption scheme's strength was assessed using standard security analysis methods and its pixel randomness was determined by the proposed test.
In this paper we have proposed a new test for pixel randomness using non-parametric method in statistics. In order to validate this new non-parametric test we have designed an encryption scheme based on 2D cellular automata. The strength of the designed encryption scheme is first assessed by standard methods for security analysis and the pixel randomness is then determined by the newly proposed non-parametric method.
