Internet of Things (IoT), Security Protocols, Lightweight Cryptography, Resource-Constrained Devices, Communication SecurityAbstract
IoT devices in cyber-physical systems and daily applications have expanded, ushering in linked intelligence. However, these devices' minimal processing power, memory, and battery life make communication channel security difficult. However, resource-constrained IoT devices cannot use traditional encryption, which is resilient but memory- and processing-intensive. This requires researching lightweight cryptographic techniques that balance IoT security with resource efficiency.
This study evaluates prevalent lightweight IoT security methods. Explore three popular protocols: LSMWP, CoAP with DTLS, and Efficient Cryptographic Primitives for IoT. Multiple tests include security, performance, and IoT use case compatibility.
Security of each protocol's ciphers and hash algorithms is researched. To protect IoT data confidentiality, integrity, and authenticity, this research assesses its resilience to well-known cryptanalytic assaults. This study evaluates each protocol's key management measures to prevent key exposure and device impersonation. Last, protocol message integrity protections are tested to avoid data manipulation during network transmission.
IoT devices with limited resources must function well. Protocol processing overhead is compared using published benchmarks. Communication latency, encryption/decryption, and message signing/verification are assessed. Each protocol's memory footprint is examined, taking IoT devices' limited memory into account. Each IoT protocol is examined in the study's conclusion. Data sensitivity, device processing, and application real-time restrictions are studied. The study maps protocol pros and cons to use scenarios to help developers and security experts choose the best IoT protocol.
This detailed review examines lightweight cryptographic methods for IoT security-performance trade-offs. The insights will improve IoT ecosystem dependability by improving communication security and efficiency.
