Enhancing IoT Security through the Integration of Blockchain and SSL Protocols

Abstract

The Internet of Things (IoT) has transformed modern communication by connecting billions of devices for data collection and exchange, yet it has also posed considerable security challenges. Secure Socket Layer (SSL) encryption is commonly employed to secure communications; nevertheless, SSL by itself fails to ensure complete data authenticity, decentralization, and tamper resistance within the IoT ecosystem. Blockchain, with its decentralized and immutable nature, offers a complementary approach to addressing IoT security. This paper presents an integrated framework combining Blockchain and SSL protocols to enhance IoT security. The proposed model aims to mitigate key IoT security threats, ensuring encrypted communication, decentralized authentication, and data integrity. Furthermore, the paper discusses challenges associated with Blockchain-SSL integration, such as scalability and resource constraints in IoT devices, and provides recommendations for future research.
