Post-Quantum Cryptography Migration in Australian Real-Time Payment Infrastructure: A Monte Carlo Simulation Study of the New Payments Platform
Monte Carlo simulations of post-quantum migration in Australia's real-time payment system quantify latency impacts under strict SLAs—a methodological template European financial institutions can adapt for their own DORA-aligned PQC planning.

arXiv:2605.02276v2 Announce Type: replace Abstract: Australia's New Payments Platform (NPP) processes 5.2 million real-time transactions per day under a 2,000 ms end-to-end SLA. With cryptographically relevant quantum computers projected for 2030-2035, financial institutions face a post-quantum cryptography (PQC) migration requirement. This paper presents a simulation study of the NIST FIPS 204 and 205 signature standards (ML-DSA, SLH-DSA/SPHINCS+) together with the NIST-selected Falcon algorit
Editorial Analysis
European financial institutions face similar PQC migration challenges under DORA timelines; this study's quantitative approach to latency and performance trade-offs provides actionable planning data.
Adapt the Monte Carlo simulation methodology to your own real-time transaction infrastructure to quantify PQC migration risks before regulatory deadlines.
Quantitative modelling of post-quantum cryptography migration in payment systems shows measurable latency impacts that require early planning to meet regulatory deadlines.
