In this paper, we propose an improved chaotic map by coupling two existing methods. Numerical tests prove that the proposed technique presents closely complex behaviour and …
In this work, we use an improved fractional-order logistic map to introduce a new colour image encryption algorithm. By analysing the Lyapunov exponent and the bifurcation …
In this paper, we present a new image encryption approach by generating the key streams using the fractional-order logistics map, which is due to the advantages it offers such as …
