Securing Data with Lattice-based Cryptosystems

Written by Zane White

Lattice-based cryptography is a type of encryption that protects data by using the mathematical characteristics of lattices. This method is immune to attacks from quantum computers because it depends on the intricacy of specific lattice problems. An n-dimensional grid-like pattern is formed by lattices, which are geometric structures represented as sets of points. The Shortest Vector Problem (SVP) and the Closest Vector Problem (CVP), which both require locating particular vectors within these lattices, are the two primary problems that lattice-based cryptography relies on for security. Because it can resist attacks from quantum computers, this cryptographic technique is regarded as post-quantum secure. Lattice-based cryptography is a viable choice for long-term data security because of this characteristic.
