Post-Quantum Cryptography

Quantum computing has the potential to break existing cryptographic algorithms. For example, Shor’s Algorithm can factor large integers exponentially faster than the best classical algorithms. Since the security of widely used cryptosystems like RSA and ECC relies on the hardness of factoring and discrete logarithms, scalable quantum computers could render them insecure.

Why PQC matters

As quantum computers continue to grow in scale and capability, designing and deploying robust post‑quantum cryptosystems is crucial to ensure a secure technological future. Governments, standards bodies, and industry leaders are actively working on NIST’s PQC standardization to prepare for the transition.
