"djb" as he is known in the crypto world has a good paper at https://eprint.iacr.org/2024/1265 , it's 68 pages so "almost a book". He also has a lot of resources on his page https://cr.yp.to . Be aware that he is sometimes ... controversial (not racist or anything, just has strong opinions on FIPS and the NSA and has actually taken the US government to court in the past over this). He's the author of Curve25519.
