> A new type of computer is being developed that can break many of our existing cryptographic algorithms. As a result, we need to develop new algorithms that are secure against those computers and that will run on our existing computers. This is called...

> Lattice-based cryptographic systems are a whole class of systems based on hard questions around spaces formed by combining sets of vectors to form new vectors. All the new vectors you can form by these combinations are called a lattice.
