Energy Consumption Analysis of ISO/IEC 29192-2 Standard Lightweight Ciphers

The Internet of Things (IoT) is a transformative technology that enables connection and communication between devices, systems, and objects using an existing network. This interconnectivity allows these objects to collect and analyze data, facilitating interaction in various environments. IoT spans areas such as homes, industries, cities, and even ecosystems, creating smart and responsive systems. In today’s digital age, where protecting personal, industrial, and commercial information is critical, IoT technologies must ensure a high level of security. It is essential to employ secure communication protocols or applications to ensure that IoT devices with limited resources, such as embedded systems, can communicate safely. Due to the low processing and memory capacities of these devices, traditional encryption techniques like AES are often impractical. Consequently, numerous lightweight encryption techniques have been developed specifically for use in embedded systems. The first stage of this research focused on the CLEFIA, PRESENT, and LEA algorithms outlined in the ISO/IEC 29192-2:2019 standard. The second stage involved developing a test environment to run these algorithms on embedded systems, ensuring that they were compatible with the systems’ constraints. The third stage focused on determining and analyzing the real-time energy consumption of these algorithms when implemented on embedded systems.
