Comparative Analysis of Lightweight Cryptography and Blockchain-Based Security Protocols for Mitigating Threats and Vulnerabilities in the Internet of things

The uncontrolled growth of the Internet of Things, especially in securing limited-resource IoT, has created unprecedented potential that raises issues tremendously. The key intention of the study is to comparatively examine the security measures and defenses against the cyber-attacks that take place in the IoT security protocols. The study provides a combination of secure communication protocols, blockchain technology, and lightweight cryptography using Bevywise IoT simulator, MQTT Route, and Wireshark for the network. The results of the study confirm the effectiveness of the security measures provided by the blockchain technology for the integrity and immutability of the data. The results also emphasize the significance of the study to solve the IoT security issues better. By creating a security framework, the study significantly contributes to the development of IoT technology, especially in the fields where the security has to be given more priority. Cyber security and maintaining the privacy and trust of the systems play a very significant role.
