The Financial Services Information Sharing and Analysis Center (FS-ISAC) has released a comprehensive series of papers, crafted by its Post Quantum Cryptography Working Group, aimed at guiding the payment card industry (PCI) towards quantum-resilient standards.
This timely guidance comes as quantum computing emerges as both a powerful asset and a significant threat, particularly to cryptographic security that protects card transactions.
The highlighted paper, The Impact of Quantum Computing on the Payment Card Industry, primarily targets business leaders, outlining essential steps for adopting quantum-resistant cryptography.
The guidance stresses the importance of maintaining robust cyber hygiene practices, such as enforcing strong access controls, encrypting sensitive data during storage and transmission, and conducting thorough risk assessments to pinpoint vulnerabilities. These measures are crucial in mitigating quantum-related threats and enhancing the industry’s capabilities to thwart adversarial attacks.
In his statement, FS-ISAC’s Chief Strategy & Innovation Officer, Mike Silverman, underscored the dual-edged nature of quantum technology, stating, “Quantum computing will assist firms in solving problems that are too complex and time-consuming for today’s computers, yet it could threaten existing cryptographic security, such as that of the card transaction ecosystem.” He emphasises that the advice offered in the papers is a product of extensive collaboration among experts dedicated to modernising encryption methods.
Further, the guidance includes detailed use cases that elucidate cryptographic assumptions and quantum’s impacts on various PCI components like card provisioning and transaction routing. These scenarios are designed to assist PCI practitioners and technologists in transitioning to quantum-resistant cryptography effectively.
Echoing the sentiment of proactive preparation, Oscar Covers, Policy Advisor Cyber Security of the Dutch Banking Association, highlighted the financial and security benefits of early strategic planning. He remarked, “By developing a quantum migration strategy early, firms can save a lot of money and create a safety net that minimizes the risk of disruptions.”
The FS-ISAC initiative aims to safeguard the integrity of the global financial network against the potential upheavals posed by quantum computing. As the technology progresses, the need for quantum-resilient cryptographic solutions becomes increasingly imperative to ensure the ongoing security of the payment card industry.
