Noise-Crypt: Image Encryption with Non-linear Noise, Hybrid Chaotic Maps, and Hashing. (arXiv:2309.11471v1 [cs.CR])

To secure the digital images over insecure transmission channels, a new image
encryption algorithm Noise-Crypt is proposed in this paper. Noise-Crypt
integrates non-linear random noise, hybrid chaotic maps, and SHA-256 hashing
algorithm. The utilized hybrid chaotic maps are the logistic-tent and the
logistic-sine-cosine map. The hybrid chaotic maps enhance the pseudorandom
sequence generation and selection of substitution boxes, while the
logistic-sine-cosine map induces non-linearity in the algorithm through random
noise. This deliberate inclusion of noise contributes to increased resistance
against …
