Lecture #3 part3: Public Key Cryptography 101: A Brief Introduction | Joseph H. Silverman

Series of lectures on the Introduction to Lattices, Lattice Reduction, and Lattice-Based Cryptography. Lecture #3: Public Key Cryptography 101: A Brief Introduction

A lattice is a discrete subgroup of R^n. We will discuss the theory of lattices and describe how they have been used to construct practical public key cryptosystems and digital signature schemes that are, at least presently, secure against attacks by quantum computers.
