Hardware software co-simulation of dual image encryption using Latin square image

Abstract

Hardware Software co-simulation of a multiple image encryption technique has been described in the present study. Proposed multiple image encryption technique is based on Latin Square Image Cipher (LSIC). First, a carrier image based on Latin Square is generated by using 256 bits length key. XOR operation is applied between an input image and Latin Square Image to generate an encrypted image. Then XOR operation is applied between encrypted image and second input image to encrypt second image. This process is continues till nth input image. The proposed multiple image encryption technique is implemented Xilinx System Generator (XSG). This encryption technique is modeled using Simulink and XSG Block set and synthesized onto Virtex 2 pro FPGA device. Proposed technique is validated using hardware software co-simulation method.
