Efficient Security for Resource-Constrained Devices with LPM: A Lightweight Protocol Utilizing Chaotic Map-Based S-Box
K. Ramesh · 2024
The widespread adoption of resource-constrained devices, including lightweight devices such as RFID devices, necessitates the development of encryption algorithms that effectively balance security and efficiency. In this study, we conducted a comprehensive evaluation of various lightweight block ciphers, focusing on their suitability for lightweight devices. Through our assessment, we identified vulnerabilities in the LRBC cipher, highlighting the need for improved solutions. To address these challenges, we propose the Lightweight Securing Protocol (LSP), a novel approach that leverages a chaotic map-based S-Box. Our protocol incorporates a sophisticated key scheduling scheme, integrating a permutation box and function to enhance resistance against key-related attacks while maintaining lightweight characteristics. Furthermore, we meticulously designed a highly efficient S-Box, yielding promising metric results, including an average Avalanche effect of 50%, Signal to Noise Ratio of 2.024, the sum of square indicator of 1048, and an absolute indicator of 16. Thorough analysis and detailed results are presented in the results section, affirming the efficacy and robustness of our proposed protocol.
