Glossary / Dictionary

[Vanuan]

There seems to be a disconnect between terms used in Google/Apple SDK, TCNCoalition, PACT, etc

Is there an authoritative/common glossary all contact tracing protocols can use?

Or at least, is there a glossary used in the DP-3T protocol?

Some terms for starters:

• daily tracing key / temporary exposure key / secret key for day / key for beacon id generation
• handshake / beacon
• handshake id / ephemeral id / beacon id
• contact / exposed (matched handshake or set of handshakes matched to diagnosed person)
• meeting duration / non-exposed contact (a series of handshakes / beacons traced to one device)
• diagnosis key / broadcast keys for beacons (keys shared by diagnosed individual for handshake matching by exposed individual)
• matching criteria / contact calculation / risk factors (a set of criteria to identify a contact / exposed status: duration, number of handshakes, signal strength)
