Post-Quantum Cryptography

Post-quantum cryptography is the design and adoption of cryptographic methods intended to remain secure against sufficiently capable quantum computers. Today, many public-key systems, including RSA and elliptic-curve cryptography, rely on mathematical problems that a large quantum computer could solve much faster than a classical one. Post-quantum schemes use different foundations, such as lattice-based, hash-based, or code-based problems. For AI organizations, this is not only a distant research topic. Model artifacts, training data, customer prompts, agent logs, and digital signatures may need to stay confidential or trustworthy for many years. Data encrypted today can be stored and attacked later, and AI-assisted analysis may also accelerate the discovery of weaknesses in protocols, implementations, and key management. Post-quantum cryptography is therefore part of security architecture: knowing which systems depend on vulnerable algorithms, which data has a long confidentiality horizon, and how to migrate without breaking APIs, certificates, or compliance controls. Without that map, risk often stays hidden until vendors or regulators force a rushed change.
