Classical, Quantum, and Post-Quantum Cryptography: The Differences Classical cryptography uses difficult mathematical problems to protect data from non-quantum threats. Post-quantum cryptography also relies on mathematical problems, but they’re much more difficult than in classical cryptography and can withstand quantum attacks. Classical cryptography encompasses the standard encryption algorithms that pretty much every business or government entity uses today to protect its data. Post-quantum cryptography, or PQC, is an evolution of classical cryptography. However, PQC extends classical cryptography’s property of intractability to quantum computers. Post-quantum cryptography systems are mainly asymmetric (public-key), though there are symmetric systems in development as well. Just like post-quantum cryptography, quantum cryptography’s aim is the protection of data from quantum threats.
