Mandatory Physical-Digital State Attestation Utility

The Mandatory Physical-Digital State Attestation Utility (MPDSAU) represents a fundamental, systemic architectural layer required for the continued operation of hyper-interconnected critical infrastructure in high-density operational environments. As utility networks—including smart electrical grids, autonomous transportation matrices, and industrial Process Control Systems (PCS)—become increasingly reliant on real-time sensor data to execute physical actions, the surface area for cyber exploitation has expanded beyond traditional network vulnerabilities. The primary function of MDSAU is to provide cryptographic assurance that reported digital states are not only provably traceable but also physically plausible according to established local laws, environmental constraints, and known operational physics models. This utility moves cybersecurity from merely verifying data integrity (provenance) to enforcing physical reality congruence (plausibility).
