Important Terms and Notation For the purposes of this post, it is important to understand a few basic notation and terms. We define further linear algebra terms inPart 1 [https://writing.chelseakomlo.com/
This post gives a (hopefully!) simple introduction to lattices and hard problems based on lattices. In Part 2, we’ll look at one simple lattice-based key exchange, to understand how to use these underlying hard problems in cryptosystems.
