oai:localhost:PNK-73552023-03-31T01:30:11Z An extendable key space integer image-cipher using 4-bit piece-wise linear cat map Gaetan Gildas Gnyamsi, Nkuigwa Hermann Djeugoue, Nzeuga J. S. Armand Eyebe, Fouda based on a 4-dimensional PWLCM CC BY This paper presents a multiplierless image-cipher, with extendable 2048-bit key-space, based on a 4-dimensional (4D) quantized piece-wise linear cat map (PWLCM). The quantized PWLCM exhibits limit-cycles of 4-bit encoded integers with periods greater than 107. The synthesis of the PWLCM in a finite state space allows to eliminate the undesirable finite precision effect due to the hardware realization. The proposed image-cipher combines chaos, modular arithmetic, and lattice-based cryptography to encrypt a color image by performing pixel permutation and diffusion in a single operation. Further, an image-dependent confusion operation based on an 8-bit 2D-PWLCM is performed on the whole image to enhance security. 2023-03-31T01:30:11Z 2023-03-31T01:30:11Z 2023 Book https://link.springer.com/article/10.1007/s11042-022-13779-y https://dlib.phenikaa-uni.edu.vn/handle/PNK/7355 en application/pdf Springer |
