The approach outlined by Apple and Google is very similar to, and likely based on, the TCN protocol developed by a coalition of open source projects. If you'd like to discuss possible vulnerabilities and propose further improvements, there's an active community already doing that who would be happy to have one more contributor. :-)

Thank you, I'll take a look into TCN and the protocol.

Do you know whether TCN have worked with and/or compared notes with OpenTrace[1]?

I’m part of the CoEpi project, one of the member projects of the TCN Coalition. I see that some of my teammates are searching through the OpenTrace code to see if anything there is worth taking, such as their device-specific bluetooth range calibrations. I don’t think there’s been any two-way communication between these teams.

The projects I've seen inside of TCN seem aware of OpenTrace and the code / data they put out over the last few days, not sure if direct contacts exist yet.
