# Energy Consumption Analysis of ISO/IEC 29192-2 Standard Lightweight Ciphers
## 1 Introduction  
ARPANET, which was created in 1969 with the initial idea of connecting only a few systems, has today become a vast separate world where billions of computers and systems come together. The speed, capacity and traffic of the Internet has increased exponentially, reaching today and extending into the future. Today, mobile devices that almost everyone carries in their pockets have superior capabilities compared to the supercomputers of 20 years ago. Now, human beings can make almost all devices smart thanks to microsensors and smart chips. Smartphones, cars, and heating systems have become easily controllable and programmable. In the last decade, applications developed within the scope of the Internet of Things (IoT) have started to take place in our lives quietly and gradually with the advancement of sensor and communication technologies. Globally, the number of things that can be characterized as devices and connections is growing faster than the human population. Therefore, this accelerates the increase in the average number of devices and connections per household and per person. Every year, new devices in different forms with increasing capabilities and intelligence are being introduced and adopted. In a vast and dynamic ecosystem, IoT applications introduce a range of emerging challenges. As the commitment of people, businesses and countries to Internet of Things applications increases, the desire of hackers and malicious people to access and steal data increases. Therefore, security is the biggest challenge that IoT technologies must overcome. Most Internet of Things applications collect and process information to facilitate people's daily lives. Since most of these data can be characterized as personal data, privacy issues arise. The development of cryptographic standards has evolved to keep up with the increasingly complex security demands of our highly interconnected world. Early encryption methods like DES (Data Encryption Standard) laid the foundation but eventually became outdated as advances in computing power and cryptanalysis made them vulnerable. This led to the introduction of AES (Advanced Encryption Standard), which provided more robust security and improved efficiency [1]. Although AES is still a powerful and widely used standard, its high computational and resource demands make it a poor fit for IoT devices and other systems with limited resources. To address this, lightweight cryptographic standards such as ISO/IEC 29192-2 [2] have emerged. These algorithms are designed to be energy-efficient and high-performing while still providing adequate security. They are tailored to meet the specific challenges of IoT environments, ensuring that devices can operate securely even with minimal processing power and memory, making robust security accessible for even the most constrained systems. There have been significant advancements in the world of information security since the block cipher algorithm AES was recognized as a standard in 2001. The AES encryption method is commonly used to secure communication between clients and servers, and is intended for use in conventional networks for standard data communication. IoT technology is now used in a variety of applications, ranging from wearables to industrial applications. The communication infrastructure in this area is not adequately secure. According to published reports, although data transfer worldwide is large, a very small part of IoT device traffic is encrypted [3]. The general objective of IoT devices is to ensure that they operate quickly and reliably for an extended period while using minimal power. As a result, algorithms and systems that are small in size in the rapidly expanding IoT ecosystem, require less energy, and take up little space should be used. The TCP/IP protocol, which is used for standard Internet communication, is often used. On the other hand, additional security measures should be taken to increase data security to greater levels.
