post-quantum encryption

Post-quantum encryption refers to cryptographic methods designed to be secure against attacks by quantum computers. Unlike traditional encryption algorithms (such as RSA or ECC), which rely on mathematical problems that quantum computers could potentially solve efficiently, post-quantum algorithms are based on mathematical problems believed to remain hard even for quantum computers—such as lattice-based, code-based, multivariate, or hash-based approaches. These methods aim to protect data privacy and integrity in a future where quantum computing is widely available.
