摘要

Securing data in resource-limited computing devices is challenging due to limited computational power and energy resources in such contexts. In this regard, the SLCA-Cipher is a new and lightweight encryption method based on Cellular Automata. The SLCA-Cipher uses 1D Cellular Automata Rule 90 to develop effective applications in image encryption, addressing serious security needs for IoT applications. The method achieved high performance across security metrics, with a number pixel change rate (NPCR) of 99.6201, an information entropy of 7.9969, and a unified average changing intensity (UACI) of 49.9340, demonstrating its robustness against differential attacks. Comparisons with other techniques revealed that SLCA-Cipher achieves higher NPCR and UACI values and better entropy. This establishes that SLCA-Cipher effectively secures sensitive data and meets the strict requirements of low-power devices. Future work involves optimizing SLCA-Cipher for more general cryptographic purposes and evaluating its scalability across various IoT environments, thus enhancing its strength in lightweight cybersecurity.
