A Simple and Robust Gray Image Encryption Scheme Using Chaotic Logistic Map and Artificial Neural Network

Table 2

Correlation coefficients and entropy information between the gray image and corresponding cipher image of several USC-SIPI images databases and some medical images. The encryption has been done using the secret key “23421100452972604309100881297041.”
