Why Post-Quantum Cryptography Starts With Credentials

Quantum Computing / Non-Human Identity
Today’s encrypted data, such as credentials, may no longer remain confidential in the future because the public-key cryptography protecting it will soon be broken by quantum computers. Although no machine today can break elliptic curve cryptography or RSA, quantum hardware is advancing rapidly and will inevitably change how organizations protect their data. Ciphertext and credentials captured by attackers can now be stored and decrypted as soon as quantum computing catches up. How urgent is quantum-resistant cryptography? The Global Risk Institute’s 2025 Quantum Threat Timeline report shows that surveyed security specialists believe a cryptographically relevant quantum computer is likely to be available within 15 years, with 51-70% indicating so. The threat dates back to 1994, when Peter Shor proved that a powerful quantum computer could efficiently factor large numbers and compute discrete logarithms. However, Shor’s algorithm applies to public-key cryptography, posing no meani...
