Central Bank Digital Currency Cybersecurity: Threat Modeling Sovereign Digital Money Against Quantum Adversaries

A threat modeling framework for central banks evaluating quantum threats, offline payment risks, and system-level resilience.

Nation-State Attack Vectors Against Sovereign Digital Currency

Unlike commercial banking systems where financial fraud is localized, a successful attack against a central bank digital currency can destabilize a nation's monetary sovereignty. Nation-state adversaries equipped with cryptanalytically relevant quantum computers will target central bank minting master keys and interbank clearing hubs.

Offline Payment Security and Double-Spending Mitigation

Designing offline retail CBDC capabilities that survive total telecommunication or power grid blackouts. We analyze hardware-enforced trusted execution environments (TEE) and post-quantum zero-knowledge proofs that prevent double-spending in offline hardware devices.

Privacy vs Regulatory Oversight: The Technical Compromise

Architecting selective privacy models that preserve consumer privacy for small-value everyday transactions while providing cryptographically verifiable audit trails for high-value wholesale transfers to enforce AML/CFT mandates.
