Subject: [saag] Fwd: IETF 102 Remote Attestation Procedures (RATS) Bar BoF Invite

From: Carsten Bormann <[email-masked]>

So, just for completeness and to minimize confusion about Bar BoFs in Montreal:
There will be a Bar BoF about remote attestation work at IETF on Thursday (19th) evening.
This is different from, and in addition to, the EAT-shaped one on Monday (16th).
See buried in the thread below.

Grüße, Carsten

The EAT token may play a role in such a flow (after a number of technical issues have been resolved), but there is more to attestation than a token data format (it wouldn't even be totally wrong to say that there is no actual attestation in EAT).
