MAES: Modified advanced encryption standard for resource constraint environments

摘要

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. But due to recent emerge of IoT devices, the main concern is shifting to moderate security and less energy consumption rate. We present MAES, a lightweight version of Advanced Encryption Standard (AES) which meets the demand. A new 1-dimensional Substitution Box is proposed by formulating a novel equation for constructing a square matrix in affine transformation phase of MAES. Efficiency rate of MAES is around 18.35% in terms of packet transmission which indicates MAES consumes less energy than AES and it is applicable for Resource Constraint Environments.
