latticealapú
Latticealapú, or lattice-based cryptography, refers to cryptographic constructions whose security is based on the hardness of mathematical problems in lattices, multidimensional grids of points in Euclidean space. These systems aim to provide strong cryptographic primitives while offering resilience to quantum attacks.
The security backbone of latticealapú cryptography typically rests on problems such as learning with errors (LWE),
Historical development began with Ajtai’s introduction of LWE in the mid-1990s, followed by Regev’s cryptographic applications.
Applications and standardization efforts are ongoing. In modern practice, lattice-based methods underpin many post-quantum standards and
