Hi Henk, Laurence, Thank you for confirming my understandings. Your comments really help me to read current drafts. :-) Thanks, Yuhei 2019年11月1日(金) 23:25 Laurence Lundblade <lgl@island-resort.com>: > Hello, > > A frame up that works for me is to think about 1) the claims, the > attestation format and its details and 2) the transport / conveyance and > its details. > > In the TPM/TCG world the claims and attestation format is locked down by > what TPM chips do today.
