Blockchain-Enabled Access Control in Smart Homes
Word Count : 5000
Objectives to cover:
Introduction: Blockchain is used to secure and manage access control in smart homes by ensuring trusted and tamper-proof interactions between devices and users.
Decentralized Identity Management: Each device and user gets a unique blockchain identity that prevents unauthorized access.
Smart Contract-Based Access Policies: Automated rules stored on blockchain manage who can operate which device without manual intervention.
Immutable Access Logs: Every access request and action is recorded securely to track intrusions and misuse.
Role-Based Permission Control: Permissions are granted based on predefined user roles for enhanced household safety.
Device-to-Device Trust Establishment: Devices authenticate each other through blockchain to prevent spoofing attacks.
Secure Remote Access Authorization: Blockchain verifies legitimate remote users before allowing home system control.
Resistance Against Single Point of Failure: Distributed storage eliminates risks caused by central server hacks.
Enhanced User Privacy Protection: Sensitive access data remains encrypted and only visible to authorized parties.
Scalable Integration for Multi-Vendor Devices: Ensures interoperability and secure access across products from different manufacturers.
Conclusion: Blockchain strengthens access control in smart homes with secure authentication, transparency, and resilient protection against evolving cyber threats.
