FPGA Hardware Co-Simulation of Image Encryption Using Stream Cipher Based on Chaotic Maps

In this paper, new model of image encryption system using stream cipher based on fixed point chaotic maps are designed using Xilinx System Generator (XSG) in efficient way. Two Pseudo Random Bit Generators (PRBGs) depends on chaotic maps are proposed that are Fixed Point XOR Chaotic Map-PRBG (FPXORCM-PRBG) and Fixed Point Cascade Chaotic Map-PRBG (FPCCM-PRBG). The randomness tests in the National Institute of Standards and Technology (NIST) are...
