Awesome content & I can not stop myself to watch rest of the videos from this playlist at one go.... Please watch such a wonderful series to understand one of the major concepts left behind within dev community....🙂
Does AEAD have to do with the introduction of QUIC as a new/3rd transport later protocol that runs over UDP, but establishes the security/encryption arrangement over a single back and forth packet exchange? I just saw a Chris Greer video about QUIC and was left thinking, ' there's a new layer 4 protocol and my instructors haven't even mentioned in the prior 2 years?! WTF?'. It seems like kind of a big deal if we've only had two layer 4 protocols for over 30 years, and there is now a new-ish one.
Good question! Yes, QUIC is the new L4 protocol, a lot of research went in to QUIC and it will likely replace TCP/UDP at some point in the future. As for AEAD... no, QUIC/AEAD are unrelated. It might be that QUIC encryption will use an AEAD cipher, but they are independent concepts. Cheers, Scott!
@@PracticalNetworking damn. I was thinking AEAD in one back and forth seemed to be what QUIC was doing, so I figured it was what allowed QUIC to be as awesome as it is. Clearly there is more I need to understand about why this isn't the case. I'll try to dig into that (as time allows), and totally look forward to any more possible videos digging into AEAD (or QUIC, for that matter). Thanks SO MUCH, Ed, for creating the content you do! 👍 It is so appreciated by so many of us.
No, the version ties to how/what/when things are encrypted/hashed/etc on the wire... so if they are doing different versions, they will never "understand" each other. It's like different languages.
