We live in an interconnected world, and digital data transmissions have reached significant importance as they are the most used means of communication. Connected objects widely our life, yet may pose vulnerabilities risks such hacking or personal theft due to their often inadequate security. In response size capability restrictions many existing embedded devices, lightweight cryptography has been considered. This article describes a hardware implementation cryptographic method [very high speed integrated circuit description language (VHDL) field-programmable gate arrays (FPGAs)]. work presents solution for securing information, more specifically images, ensure level security favorable performance, robust algorithm with respect Shannon's theory, Chaos, its implementation. The is block cipher scheme that treats 128-bit length. paper discusses method's two main parts: key generator-based chaos consists whitening operation, random permutation, key-dependent S-box. Both generator encryption implemented using VHDL on Xilinx ZedBoard Zynq Development Kit platform. generated sequences tested NIST SP 800-22 test suite. proposed capable different gray-scale images while maintaining low power usage, good frequency 129.9038 MHz, throughput 1651.201 Mbps. statistical differential attacks demonstrate cryptosystem effective against next generation attacks.
