Rethinking Federated Identity Management: A Blockchain-Enabled Framework for Enhanced Security, Interoperability, and User Sovereignty
Keywords:
Federated Identity Management, Blockchain, Decentralized IdentityAbstract
Online user access management changed with FIM. Single Sign-On from FIM enhances IdP and SP user efficiency. Traditional FIM uses insecure centralized IdPs. Single-point attacks on these vulnerabilities might access large data collections. Centred solutions restrict IAM system compatibility and prevent identity data from traversing business boundaries.
This research decentralizes federated identity management using blockchain. IAM is safe, user-centric, and future-proof due to its decentralized platform.
The design uses IdP-SP attribute swapping. Interoperability makes identity management more versatile than FIM. Importantly, the technology enables users unmatched ID data control. User approval is done using tamper-proof smart contracts. Users only reveal the minimal service attributes in smart contracts using fine-grained Attribute-Based Access Control (ABAC). Granular attribute disclosure restrictions protect user privacy and reduce attacker surface.
