A Gentle Introduction to Lattice-Based Cryptography [pdf] (cryptography101.ca)

Oh this brings me back to my uni days. I suppose that since this is the basis of post-quantum crypto it is a good time to learn this.

Seems to me that these lattices and error-correcting codes are very close to each other, but for some reason they are discussed separately.

I'd wager that there will be some reductions between those problems - maybe I could dig more around that.

A nice (short!) video on this topic is this one from Chalk Talk: https://youtu.be/QDdOoYdb748?is=vCFGroHUPwZP7Dqm

Good stuff to know, just in case the life extension tech explodes and we're all alive by the time cryptographically relevant quantum computers actually hit the scene.

I've implemented ML-KEM by the spec as an exercise recently (https://github.com/AlexanderYastrebov/mlkem) and here are related links that helped me understand the math:

* [Enough Polynomials and Linear Algebra to Implement Kyber](https://words.filippo.io/kyber-math/)

* [Basic Lattice Cryptography. The concepts behind Kyber (ML-KEM) and Dilithium (ML-DSA)](https://eprint.iacr.org/2024/1287.pdf)

* [A Complete Beginner Guide to the Number Theoretic Transform (NTT)](https://eprint.iacr.org/2024/585.pdf)

It's a superficial point but this relatively newer style (La)TeX layout makes me much more keen to read documents for some reason.

So let’s say this is wildly over my head… what would be some good places to start reading to gain a minimal foundation to engage with this?
