Simulating Resilience In Blockchain-Backed Log Management For Digital Cultural Heritage Against Insider Threats

Abstract


Securing cultural heritage digital archives is critical, yet centralized log management remains vulnerable to administrative manipulation. To address the lack of empirical resilience against privileged insider threats, this study evaluates a Zero Trust blockchain architecture for preserving artifact provenance. A discrete-event simulation (SimPy) modeled an "Ex_Curator" attack injecting 10,000 unauthorized requests per hour against an ECC/SHA-256 validated ledger. The architecture successfully intercepted all anomalies while maintaining a flat queue and a stable 0.05-second processing latency. Hardware efficiency was exceptional, recording only a +1.05% CPU overhead and a 544 KB disk footprint. This lightweight framework ensures absolute non-repudiation for digital twins, providing a practical security solution for resource-constrained museums.
