IoT Edge Device Security: An Efficient Lightweight Authenticated Encryption Scheme Based on LED and PHOTON

IoT devices and embedded systems are deployed in critical environments, emphasizing attributes like power efficiency computational capabilities. However, these constraints stress the paramount importance of device security, stimulating exploration lightweight cryptographic mechanisms. This study introduces a architecture for authenticated encryption tailored to requirements. The combines LED block cipher with authentication PHOTON hash function. Leveraging shared internal operations, integration bases optimizes area–performance tradeoffs, resulting reduced consumption logic footprint. is synthesized simulated using Verilog HDL, Quartus II, ModelSim, implemented on Cyclone FPGA devices. results demonstrate substantial 14% reduction area up 46.04% decrease contrast individual designs PHOTON. work highlights potential efficient solutions resource-constrained environments.
