Hybrid BYOS/TKV Protocol Proposal #77

Open dmdabbs opened 2 months ago

dmdabbs commented 2 months ago

I was unable to attend the 3 July call and am catching up from the meeting notes posted today.

  • Hybrid protocol – modify v2 protocol so that a single request can go to both BYOS and TKV servers. This is meant to be a temporary measure, and when the enforcement starts only TKV mode will be supported. The benefits of the hybrid protocol are:

    • enables piecemeal migration. AdTechs can migrate pieces of their logic and asses the cost/latency and other parameters before fully committing
    • allows keeping parts of the logic that are not currently supported by TKV in BYOS, while moving the rest to TKV.

  • Encrypted + plain text payload.

  • Encrypted visible only on tee-kv

  • Current byos acts as orchestration + lookup, can see plaintext only

Is there a doc that proposes how a buyer would opt into the new behavior, &c.?

Itay: Value 2: Enables extra signals on the buyer side (page url and couple of other things).

Yes, full page url has been discussed. What other things are under consideration?

Hello David,

Your questions above should be covered once we publish public explainers.

Thank you, Alexander
