Description

Introduction

As the Internet of Things (IoT) continues to grow, managing the identity and security of devices becomes increasingly critical. Traditional identity management systems are centralized, which can lead to vulnerabilities and inefficiencies. Decentralized identity management (DID) provides a promising solution by leveraging blockchain technology to create a more secure, privacy-preserving, and scalable identity system for IoT devices. This course explores the concept of decentralized identity management for IoT devices, its benefits, challenges, and how to implement it using modern blockchain solutions.

Prerequisites

• Basic understanding of IoT devices and their communication protocols (e.g., MQTT, CoAP).
• Familiarity with blockchain technology and concepts such as smart contracts and decentralized applications (dApps).
• Knowledge of current identity management systems and their limitations.
• Experience with programming languages such as Solidity (for Ethereum) or other blockchain development frameworks.
• Understanding of cryptographic techniques used for identity verification and data security.
