TPM_E_DAA_INPUT_DATA0
The protocol checkpoint
TPM_E_DAA_INPUT_DATA0 (0x80280051) belongs to TPM 1.2 Direct Anonymous Attestation. The base What Is page already shows the short Windows message; the additional diagnostic value is that this result marks the first DAA input parameter fails the stage-specific consistency check.
The first producer to identify for this HRESULT is the staged DAA enrollment or signing state machine. Direct Anonymous Attestation in TPM 1.2 is a multi-stage protocol. Each stage consumes issuer data, TPM-specific state and outputs from earlier stages, so the first inconsistent transcript element is more useful than the final generic application failure.
Read this result as its own boundary in a sequence, not as a verdict that every TPM feature is broken. The sequence reaches the first DAA input parameter fails the stage-specific consistency check, and the component returns 0x80280051 before the application can safely assume that later key, attestation, boot or licensing work occurred.
What to preserve before retrying
- Request identity: exact function or command, input lengths, flags, caller context and this result.
- State identity: DAA stage, exact inputData0 bytes and length, issuer parameters, prior stage outputs, nonce values, and serialization version.
- Platform identity for this HRESULT: TPM generation, manufacturer/firmware revision, Windows build and relevant service events.
- Binary identity: preserve opaque structures byte-for-byte and log
0x80280051in hexadecimal.
Minimal reproduction
Recompute inputdata0 from a clean transcript and compare byte-for-byte before resubmission. Keep every other this result test condition unchanged. If the comparison reaches a later checkpoint, then the original the condition has been isolated even when a second defect remains.
| Observed outcome | Interpretation |
|---|---|
| The exact request succeeds | The changed condition belongs to the rejected the first DAA input parameter fails the stage-specific consistency check. |
| A more specific earlier code appears | Preserve the earlier result in the result trace; the previous trace probably lost the first producer. |
| The same code returns with identical bytes | Escalate the persistent it with firmware, service and command evidence rather than broad configuration changes. |
| The code disappears only after destructive reset | The result experiment is not diagnostic because original protected state and evidence were removed. |
Nearby codes with different meanings
| Nearby constant | Why it is different |
|---|---|
TPM_E_DAA_INPUT_DATA1 | The consistency check on DAA parameter inputData1 has failed — a separate checkpoint when compared with it. |
TPM_E_DAA_RESOURCES | The DAA command has no resources availble to execute the command — a separate checkpoint when compared with it. |
TPM_E_DAA_ISSUER_SETTINGS | The consistency check on DAA_issuerSettings has failed — a separate checkpoint when compared with it. |
For this page, the useful contrast is: TPM_E_DAA_INPUT_DATA1 identifies the second stage input instead.
Resolution criteria
Apply the narrow remedy: rebuild the current DAA transcript from authenticated prior outputs rather than patching the rejected field. 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.
Close the incident only when the same API or TPM command passes with the intended hardware-backed behavior and the expected output can be independently validated.
