As the Internet of Things (IoT) continues to expand, billions of interconnected devices are now transmitting sensitive data across smart homes, healthcare systems, autonomous vehicles, and industrial applications. However, traditional cryptographic algorithms are often too resource-heavy for IoT devices with limited memory, processing power, and energy supply.
To address this challenge, researchers are developing lightweight cryptosystems designed specifically for pervasive computing environments. These cryptosystems focus on delivering high-level security while consuming minimal computational resources. Unlike conventional encryption standards such as AES or RSA, lightweight cryptography employs optimized algorithms, reduced key sizes, and hardware-efficient designs.
Applications of lightweight cryptosystems extend to smart sensors, wearable devices, RFID tags, and edge computing nodes, ensuring data confidentiality and integrity without draining device batteries. The emerging standards from NIST’s Lightweight Cryptography project highlight the global urgency of securing IoT ecosystems against evolving cyber threats.
In the coming years, the adoption of secure lightweight cryptosystems will be a game-changer in IoT security, paving the way for trustworthy and resilient pervasive computing environments.
