[Ppm] New comers: Real World Crypto talks on PPM

[Christopher Patton <[e-mail]>]

Hi Aggregators,

For those who don't know, there were a couple of talks at RWC 2022 (
https://rwc.iacr.org/2022/) about our work. New folks might find it useful
to watch the recordings ahead of the meeting at IETF next Thursday.

1. The first talk describes the Exposure Notifications Privacy Analytics
(ENPA) platform developed jointly by Apple, Google, ISRG, and other
organizations. ENPA is a deployment of Prio, now one of the VDAFs we're
working to standardize ((
https://datatracker.ietf.org/doc/draft-irtf-cfrg-vdaf/). This deployment
provided loads of useful insights that we've incorporated into the design
of DAP (https://datatracker.ietf.org/doc/draft-ietf-ppm-dap/).

2. The second talk describes the motivations of the PPM working group and
outlines the approach taken by DAP to standardize multi-party computation
for privacy-preserving measurement. The talk also includes an overview of
VDAFs and the current candidate constructions.

A recording of both talks can be found here:

Sorry about the poor quality. This is the Zoom session recording.
High-quality recordings, like those for other talks at RWC, are
unavailable, apparently due to AV issues during the session.

Also, note that these talks predate the adoption call for DAP and refer to
it as the "PPM protocol".

Happy aggregating,
Chris P.
