The text in section 5 is still a bit misleading (esp. re encrypted:wallet provider clientid and encrypted:authentication context) and the information about verifier authentication is missing in the current revision.

The fundamental idea of the draft is to use the messages defined in the OID4VP base spec and send them over a secure BLE connect. The description of the actual OID4VP message exchange starts at Section 7.

Section 7.2 states "The Request contains a signed request object containing the parameters as defined in [OpenID4VP].“ but does not explain the rest.

The wallet can authenticate the verifier using this signed OID4VP request object, that is sent through the BLE connection.

It is still an early draft, we will improve the text. So thanks for raising that issue.

best regards,
Torsten.
