Lattice-Based Cryptography is a type of encryption that relies on mathematical structures called lattices. These lattices consist of points in multi-dimensional space and are used to create hard problems that are difficult for computers to solve. This makes lattice-based systems potentially more secure against attacks from quantum computers compared to traditional cryptographic methods. One of the key advantages of lattice-based cryptography is its ability to support various cryptographic functions, such as digital signatures and encryption. Researchers are actively exploring these systems as a foundation for post-quantum cryptography, which aims to protect data from future threats posed by quantum computing advancements.
