Quantum Security for Payment Ecosystems: How Certification Can Help
The payment industry is entering a new phase of cybersecurity planning . Artificial intelligence is changing how organizations detect and respond to threats, but another technology could fundamentally change how payment data is protected: quantum computing. Modern payment ecosystems depend heavily on cryptography to protect cardholder data, authenticate transactions, secure APIs, protect digital identities, and maintain trust between banks, merchants, payment processors, fintech companies, and technology providers. Many of these systems use public-key cryptography such as RSA and Elliptic Curve Cryptography (ECC), which could eventually be vulnerable to sufficiently powerful quantum computers. Although large-scale quantum computers capable of breaking today's cryptography are not commercially available, preparing for the post-quantum era can take years. Organizations therefore need to understand their cryptographic exposure, plan migration strategies, and develop professionals w...
