I have read through https://github.com/quicwg/base-drafts/pull/3120 and related issues (https://github.com/quicwg/base-drafts/issues/3274 https://github.com/quicwg/base-drafts/issues/3014) and wonder if we can have it similar to Initial Packet encryption instead. I understand we already have consensus but wonder if we can make the protocol simpler. In initial packet, the initial AEAD is calculated from Destination CID. So I propose we remove pseudo-packet concept and build AEAD from Original Destination CID to encrypt the retry token just like Initial packet encrypting its token, packet number and payload. I see the benefits are: - Consistent packet encryption mechanism, more code resuse (please) - No additional buffer to build pseudo-packet - Easier to have custom protocol (or next version) to use chosen AEAD, i.e. CHACHA20_POLY1305 - Can apply to other packets in future (e.g Version Negotiation) -- You are receiving this because you are subscribed to this thread.
