Lattice-Based Post-Quantum Cryptography

Lattice-based cryptography is a promising approach to post-quantum security. It leverages the hardness of problems related to lattice structures, which are discrete geometric arrangements of points in multidimensional spaces. This approach is believed to be resistant to attacks from both classical and quantum computers. Lattice-based schemes can be used to construct a wide range of cryptographic primitives, including encryption, digital signatures, and message authentication codes. Recent advancements have focused on improving efficiency and practicality, making lattice-based cryptography a valuable tool for securing communications in the quantum era.
