Andrew,
Under the item "securing the issue of credentials," or maybe under
"helping users to secure their credentials," somewhere in the system
needs a backup server to work (maybe in a MyProxy position). This is
necessary in case the user's TPM breaks down. This means that a user
private key can be exported from a TPM to the backup server when the
key is generated.
While a user's mission critical data can be recovered by working with
the backup server, an attested remote execution (eg, for secure
multi-party computation, SMPC) should use a non-exportable key
(attestation identity key, AIK), therefore existing a backup server
can't damage SMPC.
Just my few pence (or US cents in Chicago:-)
