Quantum computers are under active development and if they ever become sufficiently powerful they could be used to break a lot of the cryptography that is used today. In this talk, I will begin by describing Shor's quantum algorithm for integer factorization, as it is this algorithm that breaks essentially all asymmetric cryptography that is used today. Because of Shor's algorithm, there is a need for post-quantum secure cryptography and I will also present the basics behind post-quantum secure lattice-based cryptography.
