Decentralized Identity Management for IoT Devices Using IOTA Blockchain Technology

·

Introduction

The Internet of Things (IoT) is rapidly expanding, connecting billions of devices worldwide. However, traditional centralized identity management systems struggle with scalability, security, and privacy concerns. This article explores a decentralized identity framework leveraging IOTA Tangle, a blockchain alternative, to empower IoT ecosystems with secure, scalable, and user-centric solutions.


Key Challenges in IoT Identity Management

  1. Single Points of Failure: Centralized systems are vulnerable to attacks.
  2. Scalability Issues: Handling millions of IoT devices requires distributed solutions.
  3. Data Privacy: Users need control over their identity data.

IOTA Tangle: A Decentralized Solution

What Is IOTA?

IOTA is a permissionless, feeless DAG-based ledger designed for IoT. Unlike traditional blockchains, it uses the Tangle structure, enabling:

Core Technologies


Proposed Framework

Step 1: DID Integration

Each IoT device gets a unique DID, stored on the Tangle.

Step 2: Verifiable Credentials (VCs)

Step 3: Secure Data Streams


Benefits

| Feature | Traditional Systems | IOTA-Based Solution |
|-----------------------|--------------------|---------------------|
| Scalability | Limited | High |
| Security | Centralized risks | Decentralized |
| Privacy | Low control | User-centric |
