No description provided.

The table format is great but I worry about introducing an extra set of terms for the common functionality. Since the keys aren't actually used in precisely the same way in each scheme, I think that there's not a precise definition of what each of the new terms are, which makes me worried about introducing them. But the functionality is clearly analogous, so maybe just not including the first column of the table would highlight the similarity without having to define new terms?

[degregat]

I'm fine with that. I think it would help to be able to refer to it from the high level blocks, so just a numbering for that column?

Some additional terms

A/G	DP-3T	PACT (MIT)	PACT (UW)	TCN	Description
Broadcasting rotation interval, based on Bluetooth MAC address change interval	Epoch length, variable			Same as Interval Secret rotation	Pseudorandom Identifier Rotation Interval
Diagnosis key	Exposed key, known case key			Report	Key(s) shared publicly and synced locally
Contact	Matching contact, known case key			Doesn't specify matches	Local match of a key shared publicly to a set of encountered pseudorandom identifiers

Maybe this column should be renamed to "description/definition" and moved to the right side?

[degregat]

Should we say Token, or Pseudorandom Identifier in the building blocks, to be sufficiently general?

[Vanuan]

Maybe "rolling beacon key" is sufficiently non-ambiguous?

Why not just use the TCN term, temporary contact number?

What's the essence of this term?

• it has a short lifetime (temporary, rolling)
• it's broadcast to nearby devices (proximity, beacon, device)
• it may serve as an identifier of an event, time duration, device (device id, encounter/contact id, handshake key)
• it may be calculated from the underlying identifier
• it is globally unique per infectious period

Some other ideas:

• rolling device id
• proximity id
• contact event key
