Title:
Blockchain-based decentralized identity system: Design and security analysis
Authors: Gewu BU, Serge Fdida, Maria Potop-Butucaru, Bilel Zaghdoudi
Abstract:This paper presents a novel blockchain-based decentralized identity system (DID), tailored for enhanced digital identity management in Internet of Things (IoT) and device-to-device (D2D) networks. The proposed system features a hierarchical structure that effectively merges a distributed ledger with a mobile D2D network, ensuring robust security while streamlining communication. Central to this design are the gateway nodes, which serve as intermediaries, facilitating DID registration and device authentication through smart contracts and distributed storage systems. A thorough security analysis underscores the system’s resilience to common cyber threats and adherence to critical principles like finality and liveness.
