Quantum Computing Risks to Cryptographic Security of Payments

The rapid progression of **Quantum Computing** poses an existential threat to the cryptographic security underpinning all modern financial transactions, including those settled through RTGS, SWIFT, and digital currencies. Shor's Algorithm, specifically, threatens to break the public-key cryptography (e.g., RSA, ECC) essential for digital signatures, authentication, and secure communication. This highly specialized course provides a critical assessment of the quantum risk landscape, focusing on its implications for the long-term integrity of payment finality and confidential data. Participants will learn to evaluate the necessary transition to **Post-Quantum Cryptography (PQC)**, understand the standardization efforts by bodies like NIST, and develop a strategic, multi-year migration plan to ensure the future resilience of critical financial market infrastructures (FMIs) before a "quantum event" materializes.
