Dynamic trust management framework using blockchain for zero-trust-based authentication in BYOD environments

With evolving work patterns, employees access company resources from various devices, making traditional management approaches obsolete. Ensuring secure access is crucial. We propose a blockchain-based trust management framework utilizing smart contracts for continuous verification and behavior analysis. Suspicious activity triggers dynamic access adjustments. Blockchain ensures immutability and traceability in authentication. Our design mitigates centralization risks and enhances granularity. Experimental results show minimal time costs during verification, maintaining efficiency despite additional security checks.
