Lattice Based Security refers to a class of cryptographic algorithms whose security relies on the computational difficulty of solving certain mathematical problems on lattices. These problems, such as the shortest vector problem, are believed to be resistant to attacks by quantum computers. Lattice-based cryptography offers a potential solution for securing digital communications and data in a post-quantum computing era. It provides a robust foundation for future cryptographic standards.
