TPM_E_DAA_INPUT_DATA1
Interpret the condition first
TPM_E_DAA_INPUT_DATA1 (0x80280052) belongs to TPM 1.2 Direct Anonymous Attestation. This result means the second DAA input parameter is inconsistent with the current TPM 1.2 DAA transcript.
Build the command transcript
| Question | Evidence |
|---|---|
| What exact state was rejected? | the second DAA input parameter is inconsistent with the current TPM 1.2 DAA transcript |
| Which layer owns the result? | The staged DAA enrollment or signing state machine. |
| What must be correlated? | DAA stage, inputData1 bytes and length, matching inputData0, issuer settings, previous TPM output, and nonce linkage |
| Controlled comparison | generate inputData1 again from the same verified prior-stage data and compare its encoding |
A useful trace links three code-specific timelines: the application call, the local TBS/provider or firmware event, and the raw command/response exchange. The timestamps should describe one attempt; combining data from separate retries is particularly misleading for authorization sessions, context counters, DAA stages and lockout state.
Test one hypothesis
The one-variable check is to generate inputData1 again from the same verified prior-stage data and compare its encoding. Record the before/after state that the command is allowed to change. If the operation can have side effects, use a disposable key, session, counter or NV index rather than production material.
- Capture this result and
0x80280052at the first code-specific return boundary. - Decode the relevant state: DAA stage, issuer and TPM-specific structures, previous outputs, nonces and exact transcript bytes.
- Run the controlled comparison once and preserve both binary transcripts.
- Verify the expected output or state transition instead of relying on absence of a UI message.
Do not merge these conditions
| Comparison code | Built-in distinction |
|---|---|
TPM_E_DAA_ISSUER_SETTINGS | The consistency check on DAA_issuerSettings has failed. |
TPM_E_DAA_INPUT_DATA0 | The consistency check on DAA parameter inputData0 has failed. |
TPM_E_DAA_TPM_SETTINGS | The consistency check on DAA_tpmSpecific has failed. |
It specifically answers whether the second DAA input parameter is inconsistent with the current TPM 1.2 DAA transcript. In contrast, TPM_E_DAA_INPUT_DATA0 identifies a different parameter in the same staged protocol.
A safe recovery path
To remediate it, correct transcript construction and restart the affected DAA stage with mutually consistent inputs. Do not mix values from separate DAA attempts. The protocol is staged and transcript-bound; substituting one issuer value or nonce can make every later stage misleading.
