Understanding Post-Quantum Cryptography: Protecting Data from Future Quantum Threats 🔒

Post-quantum cryptography refers to new cryptographic schemes designed to withstand attacks from quantum computers. Since traditional methods like RSA and elliptic curve cryptography could be broken by quantum algorithms, lattice-based cryptography, code-based cryptography, and hash-based signatures are attracting attention. Standardization is underway by organizations like NIST, and practical adoption has begun.
