Post-quantum cryptography refers to cryptographic algorithms designed to be secure against quantum computer attacks. Unlike classical cryptography, which relies on problems like integer factorization or discrete logarithms, post-quantum cryptography uses mathematical structures resistant to quantum algorithms, such as Shor's algorithm. Common approaches include lattice-based, code-based, multivariate polynomial, and hash-based cryptography. These aim to protect data from future quantum threats while remaining compatible with existing systems. Research is ongoing to standardize algorithms like CRYSTALS-Kyber and Dilithium, ensuring security for applications like secure communications and digital signatures in a post-quantum world. Transitioning to these systems is critical for long-term data protection.
