Shameless plug: I wrote about all these schemes in Chapter 14 on post-quantum cryptography of Real-World Cryptography https://www.manning.com/books/real-world-cryptography?a_aid=Realworldcrypto&a_bid=ad500e09 https://www.manning.com/books/real-world-cryptography?a_aid=... These are meant as a gentle introduction to the ideas and intuitions behind the schemes. The book is recent but some of that stuff (hash-based signatures) I started writing back in 2015 and is available on my blog: https://cryptologie.net/article/306/one-time-signatures/ https://cryptologie.net/article/306/one-time-signatures/ At the time the schemes had not yet been chosen, fortunately I picked the right ones :) don't have to rewrite that chapter (yet).
