No time to lose: Why post-quantum security for financial services must start now

Post-quantum cryptography: The emerging threatThe transition to post-quantum cryptography (PQC) is becoming an urgent priority for the global financial sector due to the rapid evolution of quantum computing. Cryptographically relevant quantum computers exist only as research prototypes. However, their inevitable development threatens to compromise public-key cryptography—e.g., Rivest-Shamir-Adleman (RSA) and elliptical curve cryptography (ECC)—currently used to protect financial communications, digital signatures, and payment systems.
