Post-quantum cryptography addresses the design and deployment of cryptographic primitives and protocols that remain secure against adversaries equipped with quantum computers. Work in this area spans quantum-resistant public-key schemes, lightweight and end-to-end encryption, homomorphic encryption for secure computation on encrypted data, and zero-knowledge proofs for privacy-preserving authentication. It also encompasses quantum key distribution systems, passwordless and multi-factor authentication mechanisms, crypto agility in software, and security analyses of protocols and infrastructures exposed to quantum-era threats.
