Decentralized Device Identity Authentication

In traditional IoT architectures, device identity authentication is typically managed by centralized servers or cloud-based systems, which exposes them to single points of failure, identity spoofing, and unauthorized access risks. AIoTChain introduces Decentralized Identity (DID), granting each IoT device a unique, tamper-proof cryptographic identity, ensuring trusted interactions between devices.

Key Advantages:

• Decentralized Identity (DID): Each device has a unique identity secured on the blockchain, eliminating the need for centralized authentication, thereby reducing attack vectors.

• Public Key Infrastructure (PKI): Devices use asymmetric encryption technology (PKI-based) for authentication, enhancing security.

• Smart Contract-Based Permission Management: Device access permissions can be automatically assigned, modified, or revoked via smart contracts, enhancing security and autonomy.

Use Cases:

• Smart Homes: Ensures that IoT devices such as smart locks and cameras are authenticated, preventing hacking and device cloning.

• Industrial IoT (IIoT): Secures production data and prevents malicious modifications or unauthorized access.

• Smart Cities: Identity authentication and access control for IoT infrastructure.
