Blockchain-Enabled Zero-Trust Architecture for Secure Distributed Enterprise Networks
Harleen Kaur, Researcher, Thapar Institute of Engineering and Technology, Patiala
Abstract: Enterprises increasingly distribute resources across clouds, branch offices, and mobile users. Zero-Trust Architecture (ZTA) recommends “never trust, always verify” for per-request authorization, yet centralized identity and audit systems complicate cross-domain deployments. We propose BE-ZTA, a hybrid architecture that leverages a permissioned blockchain for decentralized identity anchoring, tamper-evident audit commitments, and smart-contract policy binding while keeping sensitive telemetry off-chain. We present design rationale, a prototype built on Hyperledger Fabric, security analysis, and performance tradeoffs. Experimental and literature evidence indicates BE-ZTA can deliver verifiable auditability and cross-domain policy coordination with acceptable latency when using on-chain/off-chain hybrids and caching patterns.
Keywords: Zero Trust, Blockchain, Hyperledger Fabric, Decentralized Identity, Access Control, Smart Contracts.
