Multiple stage image encryption using chaotic logistic map
M. Brindha · 2017
Image encryption becomes more important as lot of information is shared in the digital world. To make the algorithm efficient and more secure, multiple stages of encryption is highly appreciated. In this paper, chaotic logistic map based multiple stage image encryption using various functions is discussed. The impact of chaotic map parameters to various functions is also presented. Due to the chaotic map, there is a strong sensitivity to the keys used in the algorithm. Histogram and key sensitivity analysis are performed to prove the efficiency of the proposed algorithm.
