XYZ, TLS 1.3, and the Future of Cryptographic Protocols?

cryptographic protocols don't really seem to do well when they kind of grow the same way. It's better to build a more limited protocol like wire guard style, he says. And if you have multiple interacting protocols, "you'll probably have an end-to-end backup solution" He suggests keeping keys that are used in one protocol be also usable in another protocol.
