摘要

Lightweight block ciphers, such as PRESENT, play a crucial role in securing data for IoT devices that operate in resource-constrained environments. In this paper, the work explores how optimizing the round configuration of the PRESENT cipher can enhance its performance without sacrificing security. Through a detailed analysis, the system will evaluate different numbers of rounds to identify the most effective configuration. This findings indicate that reducing the standard 31 rounds to 28 not only speeds up the encryption process but also decreases energy consumption an important factor for IoT devices with limited power and processing capabilities. The model also introduce strategies for optimizing key scheduling and enabling parallel processing, which further improve efficiency. Experimental comparisons between the original and optimized versions demonstrate clear benefits in terms of energy usage, processing speed, and security margins. These results suggest that well-optimized lightweight cryptography can effectively protect IoT applications while remaining efficient and secure against common cryptographic attacks..
