", "time": "2023-11-09T16:48:49Z"}, {"author": "Richard Barnes", "text": "@Shane Kerr -- The basic intuition here is that if the measurement is x
, you can split it into x + r
and x - r
(for some random r
) and send those to two different people. Those people can then add up all their shares to get sum(x) +/- sum(r)
. Then whoever can get both of those shares can learn sum(x)
by adding them (and dividing by two), but not any of the individual x
values.
So basically, you need a splitting scheme (+- r
) and an aggregation scheme (sum()
) that are compatible with one another, and then things go. That's what a VDAF is.
