Hi,
I have occurred an error with Tspi_TPM_Quote, it shows that:
Tspi_TPM_Quote...
LOG_DEBUG TSPI rpc/tcstp/rpc_quote.c:46 RPC_Quote_TP: TCS Context: 0xa0c10e26
0 FAIL : Tspi_TPM_Quote returned (0x24) TPM_E_INVALID_KEYUSAGE
I use tpm_emulator and trousers, and run the code in domu of Xen.
result = Tspi_TPM_Quote(hTPM, hIdentKey, hPcrComposite, &validationData);
the hIdentKey is like this, which is in the Tspi_TPM_CreateIdentity.c ,
UINT32 initFlags = TSS_KEY_TYPE_IDENTITY | TSS_KEY_SIZE_2048 |
TSS_KEY_VOLATILE | TSS_KEY_NOT_MIGRATABLE;
result = Tspi_Context_CreateObject(hContext,
TSS_OBJECT_TYPE_RSAKEY,
initFlags, &hIdentKey);
In another code, I find that if the initFlags don't include
TSS_KEY_TYPE_IDENTITY, the Tspi_TPM_Quote can work well (also in domu). But
TSS_KEY_TYPE_IDENTITY must be used if I want to generate an AIK, isn't it?
I really don't konw what is wrong, so hoping to receive some advice. Thank you
in advance.------------------------------------------------------------------------------
