Quantum-Resistant Key Exchange: Preparing Finance for Post-Quantum Threats
Why Quantum Computing Is a Game-Changer for Finance
Financial institutions rely on cryptography to secure everything from interbank transfers to customer logins. Today’s public-key systems—RSA, Diffie–Hellman, and elliptic-curve cryptography (ECC)—base their security on the difficulty of factoring large integers or solving discrete-logarithm problems. A large-scale, fault-tolerant
