The Internet of Things (IoT) plays an essential role in connecting a small number of billion devices with people for diverse applications. The security and privacy with authentication are challenging work for IoT devices. A light-weight block cipher is designed and modeled with IoT security for real-time scenarios to overcome the above challenges. The light-weight PRESENT module with the integration of encryption (E)-decryption (D) is modeled and implemented on FPGA. The PRESENT module has 64-bit data input with 80/128/256-bit symmetric keys for IoT security. The PRESENT module performs16/32/64 round operations for state register and key updation. The design mainly uses Substitution-permutation (SP) network for state updation. The permutation layer is used to create more diffusion and confusion in the state for unauthorized access. The results and analysis of the PRESENT-80/128/256 are designed using Verilog-HDL with Xilinx Environment and implemented on Artix-7 FPGA. The PRESENT-80/128/256 module is compared with similar recent works with performance improvements. Similarly, the proposed work is compared with different light-weight algorithms with improvements for better security in IoT devices. The proposed PRESENT-256 module with 64-rounds on Artix-7 FPGA utilizes less than 2% Chip area (Slices and LUTs), works at 412.4 MHz frequency, and consumes 192 mW total power and 0.58 Mbps/slice of hardware efficiency.
