This change introduces shorter, more stable aliases for certificate key
labels used in the provisioning process. The aliases "UDS" (Unique
Device Secret) and "EXT" (External) are now used by client
applications.
The SPM service is responsible for mapping these aliases to the
underlying key labels ("SigningKey/Dice/v0" and "SigningKey/Ext/v0").
This provides a layer of abstraction, making the client-side
implementation cleaner and less coupled to the internal naming scheme.
Key changes:
- `spm`: Translates "UDS" and "EXT" labels to their full counterparts
during key retrieval and certificate endorsement. It now gracefully
handles missing certificates by returning an empty subject key.
- `ate`: The client library now accepts the key label directly from the
caller instead of hardcoding a mapping.
- `pa/loadtest`, `ate/test_programs/ft`: Updated to use the new "UDS"
and "EXT" aliases.
