        abstract = {The rapid proliferation of the Internet of Things (IoT) has introduced billions of interconnected devices across diverse domains such as smart healthcare, industrial automation, smart cities, and intelligent transportation systems. These devices, while enabling seamless data exchange and real-time decision-making, are severely constrained in terms of computation, memory, energy, and bandwidth. Traditional cryptographic algorithms, although secure, are often unsuitable for such resource-constrained environments. This gap has given rise to the development of lightweight cryptographic algorithms that aim to provide adequate levels of confidentiality, integrity, and authentication without imposing significant computational overhead.
This survey presents a comprehensive review of lightweight cryptographic algorithms, including block ciphers, stream ciphers, hash functions, and lightweight public-key schemes. The paper examines well-known algorithms such as PRESENT, SIMON, SPECK, CLEFIA, HIGHT, and ECC, with a focus on their design strategies, key sizes, block sizes, performance metrics, and implementation suitability for IoT environments. A comparative analysis is carried out to highlight trade-offs in terms of security strength, memory footprint, energy consumption, and throughput.
Furthermore, the survey identifies existing research gaps such as resistance against quantum-era threats, balancing ultra-lightweight performance with robust security, and integration with emerging technologies like blockchain and artificial intelligence. The study concludes that while significant progress has been made, further innovations are required to ensure scalable, secure, and energy-efficient cryptographic solutions for the ever-expanding IoT ecosystem.},
