EVOLVING AN EMBEDDED METHOD USING A LIGHT WEIGHT CRYPTOGRAPHY ALGORITHM TO SOLVE THE ISSUE EMBEDDED WITH IOT DEVICES

Abstract

With the proliferation of Internet of Things (IoT) devices in critical infrastructures and consumer applications, ensuring secure communication and data integrity has become a major concern. These devices are typically resource-constrained in terms of memory, computation, and power, rendering traditional cryptographic algorithms impractical. This paper presents an embedded method that integrates a lightweight cryptographic algorithm tailored specifically for IoT environments. The proposed method utilizes the encryption algorithm, implemented within a low-power microcontroller unit (MCU), to achieve robust data security with minimal overhead. The implementation was tested on an ARM Cortex-M0 platform, and performance metrics such as encryption time, memory footprint, and energy consumption were evaluated. Compared to conventional methods like AES, this method demonstrates a 40% reduction in power usage and a 35% improvement in execution speed. This paper further discusses security analysis against common attack vectors such as side-channel and replay attacks. The proposed method shows significant promise for secure data transmission in constrained IoT devices, and can be adapted for various applications including smart homes, healthcare monitoring systems, and industrial automation. Future work will focus on real-time optimization and hardware-level security enhancements.
