Advancing IoT Security: A Comprehensive Survey of Lightweight Cryptography Solutions

Abstract: A comprehensive survey of lightweight cryptography (LWC) solutions tailored to address the security challenges inherent in Internet of Things (IoT) environments. Evaluating various cryptographic primitives, including block ciphers, stream ciphers, hash functions, and elliptic curve cryptography, the study highlights the efficacy of AES and ECC in resource-constrained IoT devices. Emphasizing the necessity of lightweight cryptographic solutions amidst real-world constraints, the paper underscores ongoing research efforts and identifies future directions to fortify the security posture of IoT ecosystems. Through meticulous analysis and synthesis of findings, this survey advocates for the critical role of LWC in ensuring the resilience of IoT technologies.
