Why IoT Requires a New Security Solution
-
Distributed architecture.
-
Resource-constrained devices.
-
Centralized cloud dependencies
These weaknesses render them prime targets for man-in-the-middle attacks, data spoofing, and hijacking of the device.
How Blockchain Bolsters IoT Security
Decentralized Structure
Blockchain gets rid of single points of failure, lessening the possibility of mass network compromise.
Unalterable Data Logs
All data exchanges are encrypted, timestamped, and irreversible—perfect for device audit trails.
Authenticated Device Login
Every IoT device is listed on the blockchain with an unique identity, locking out unauthorized usage.
Smart Contracts for Automation
Secure, self-executing contracts enable devices to communicate and trade independently, minimising human intervention.
Real-World Applications
-
Smart homes: Safeguarding device-to-device communication.
-
Healthcare IoT: Protecting patient data from edge to cloud.
-
Industrial IoT: Making machinery logs reliable
