Design of Light Weight Encryption Algorithm for Data Privacy in Light Weight Devices Using 128 Bit Key

Abstract

Internet of things (IoT), internetworking of smart devices, embedded with sensors, software, electronics and network connectivity that enables to communicate with each other to exchange and collect data through an uncertain wireless medium. Recently IoT devices are dominating the world by providing it's versatile functionality and real-time data communication. Apart from versatile functionality of IoT devices, they are very low battery powered, small and sophisticated, and experience lots of challenges due to unsafe communication medium. Despite the fact of many challenges, the energy issue is now becoming the prime concern. Optimization of algorithms in terms of energy consumption has not been explored specifically; rather most of the algorithms focus on hardware area to minimize it extensively and to maximize it on security issue as possible.
