Modernizing SWIFT and Interbank Messaging with Quantum-Safe ISO 20022 Standards

Core engineering and protocols for ISO 20022 Post-Quantum Messaging.

The Global Transition to ISO 20022 Financial Messaging

The global financial ecosystem is transitioning from legacy SWIFT MT format to rich, structured ISO 20022 XML messages. While ISO 20022 provides superior data granularity for regulatory compliance and anti-money laundering (AML), its security model depends on digital signatures applied to the Business Application Header (AppHdr).

Integrating Post-Quantum Cryptographic Proofs into Banking Payloads

WCBDCVault encapsulates standard ISO 20022 payloads inside quantum-safe cryptographic wrappers. Financial institutions verify the authentic signing key of sending banks using pre-distributed central bank certificates, guaranteeing non-repudiation and message integrity across global interbank corridors.
