Author: Elson LiuBackgroundQuantum computing continues to develop at a staggering pace. With traditional cryptographic schemes—like RSA and Elliptic Curve Cryptography (ECC)—going bust in the dooming presence of advanced quantum algorithms (i.e. Shor’s algorithm), cryptographers are in urgent need of a quantum resistant solution. One of the most promising candidates is lattice-based cryptography. In this article, we’ll introduce the fundamental concepts of lattice-based cryptography and discu...
