Concretely, imagine a sensor node sampling a lot of low-quality sensors frequently. You can afford some setup (to share an AES key, generating as much shared (pseudo-)random as you want), but you want your per-measurement overhead to be small.
… it’s not the most practical, and the single-but version seems to be a toy problem, but I can imagine it being useful in some very particular cases?
- asxd 5y agoOn the hardware side, I think delta-sigma ADCs [1] might solve the same problem. They only sample 1-bit at a time, but they do so at a much faster rate than conventional ADCs. I'm a bit out of my scope here, but I think the concept is really cool. [1] https://en.wikipedia.org/wiki/Delta-sigma_modulation https://en.wikipedia.org/wiki/Delta-sigma_modulation
