Security Challenges and Lightweight Cryptography in IoT: Comparative Study and Testing Method for PRESENT-32bit Cipher

The Internet of Things (IoT) stands out as one of the most remarkable innovations in recent times, offering a promising future for global connectivity. However, the rapid expansion of IoT ecosystems has led to a significant increase in the attack surface, posing risks to platforms, computing systems, multifunction protocols, and network access ubiquity. To mitigate these risks, it is crucial to adopt secure system design and development practices. Popular security solutions such as data encryption and authentication have been widely employed in IoT systems. Nonetheless, the unique constraints of IoT platforms present challenges in selecting suitable algorithms. In this paper, we provide an overview and analysis of the security challenges in IoT along with potential solutions. Additionally, we propose a testing methodology for the PRESENT-32bit cipher, based on an analysis of prevalent lightweight cryptography techniques. Our implementation results demonstrate the advantages of this approach.
