Technology

• Presentation via the W3C Digital Credentials API with response mode dc_api.jwt.

Preconditions

1. The Relying Party is set to default_configuration_rp_1.
2. The test environment publishes default_trust_configuration_rp, and the Relying Party has loaded it.
3. Test case RP_WS_IA_MainInteraction_001a or RP_WS_IA_MainInteraction_001b passed in the same environment for the presentation flow of this test case.

Test Scenario

1. Perform a presentation for default_query_pid via the W3C Digital Credentials API in which the Conformance Wallet presents default_credential_pid in an Authorization Response that is valid except that one bit of its JWE ciphertext is flipped.
2. Perform a presentation for default_query_pid via the W3C Digital Credentials API in which the Conformance Wallet presents default_credential_pid in an Authorization Response that is valid except that one bit of its JWE authentication tag is flipped.

Expected results

1. The Relying Party rejects the presentation: its verification result reports a failure and releases no attribute value from the presentation, and the endpoint receiving the Authorization Response does not answer with HTTP status 5xx.
2. The Relying Party rejects the presentation: its verification result reports a failure and releases no attribute value from the presentation, and the endpoint receiving the Authorization Response does not answer with HTTP status 5xx.

Comments

The credential format does not affect this test case; use default_credential_pid in a format the Relying Party requests.
