| xobs | gurke: the big problem with DP3T is that it requires you to be online in order to see if your public key has been discovered. | 03:37 |
| xobs | Though that's a feature of any privacy-preserving contact tracing method. | 03:38 |
| xobs | So you'd need to run a server that polls the list. | 03:39 |
| xobs | But Simmel is compatible with that approach. | 03:39 |

| gurke | xobs: jup, had a look at it. are you aware if someone implemented dp3t on it or is working on? | 07:18 |
| gurke | xobs: i'll be investigating the interaces for exchanging the keys and "upload" of the "certifications" that someone is infected | 07:21 |
| gurke | xobs: clearly, this needs to be done out-of-band somehow | 07:21 |
| xobs | I'm not aware of anyone doing anything with it. So far, the goal has been to build a reference platform. | 07:21 |
| xobs | Having said that, I've verified that AES works, so there is enough of a foundation to start building something that speaks DP3T. | 07:22 |
| gurke | ok, really great btw | 07:22 |
| gurke | also the ultrasonic stuff - i'm still very skeptical about BLE for this purpose | 07:22 |
| gurke | i've gut a bunch of BLE controllers lying around and thought that i might try to implement that | 07:23 |
| xobs | Hmm? | 07:23 |
| gurke | however, if I can't access the APIs of the government for key exchange etc, then it's of no purpose | 07:23 |
| gurke | got some nordic chips on my desk I mean | 07:24 |
| gurke | (i.e. if that really requires google play services or so) | 07:24 |
| xobs | The "Near UltraSound" stuff is more of a pipe dream. I have some basic prototype code working over impractical ranges. | 07:24 |
| gurke | ok :-) | 07:25 |
| xobs | Impractical, as in, 3-5 cm. | 07:25 |
| gurke | but lots of bats circling around your head then? | 07:26 |
| gurke | (i have no clue of ultrasound ;-) | 07:26 |
| xobs | I'm not even doing ultrasound at this point, because my speakers can't produce it. So the goal there is to do... sound... and then change the frequencies once it's working. | 07:27 |
| gurke | ok | 07:27 |
| gurke | i'll keep you posted anyway if i find something interesting re. dp3t | 07:28 |
| xobs | Thanks! I'm curious. | 07:29 |
| xobs | I've mostly been testing against BlueTrace, since, well, that's what we've got here. | 07:29 |
| gurke | yes - clearly we have dp3t here | 07:29 |
| gurke | ok, ladderleak | 07:40 |
| gurke | https://eprint.iacr.org/2020/615.pdf | 07:41 |
| gurke | ups, wrong channel, sorry :-) | 07:41 |
| gurke | might still be of interest, though | 07:41 |
