It addresses problems like low processing power and memory while concentrating on delivering effective encryption. Trade-offs between power consumption and memory use, algorithmic efficiency, and performance optimization within platform limits are all examined in this study. All in all, it offers information about safely putting AES CBC 128 into practice on low-resource platforms for low-processor scenarios.
