Lattice cryptography

Lattice cryptography is a public-key cryptography technique that uses lattices, which are mathematical structures, to create encryption and signature schemes. Lattice cryptography is considered to be more secure than traditional public-key cryptography techniques, such as RSA and ElGamal, because it is based on problems that are believed to be difficult to solve, even with the use of quantum computers.
