Hi,
I'm using TPM emulator with tcsd-0.3.7 for testing and I'm getting some weird
behavior. I can easily create a legacy or binding key under SRK but creating of
a storage key fails. tpmd debug screen shows this:
...
tpm_storage.c:636: Info: TPM_CreateWrapKey()
tpm_handles.c:57: Debug: SRK valid? 1
tpm_authorization.c:526: Info: tpm_verify_auth()
tpm_authorization.c:527: Debug: handle = 02000000
tpm_authorization.c:539: Debug: [TPM_ST_OSAP]
tpm_cmd_handler.c:4077: Info: TPM command failed: (0x28) The key properties in
TPM_KEY_PARMs are not supported by this TPM.
...
So is it shortcoming of tpm emulator, or is it something in tcsd causing this
error? The parameters of the key are the same as in the case with legacy or
binding keys only key type is different. Here are exact key flags:
TSS_FLAG storage_key_flags =
TSS_KEY_TYPE_STORAGE |
TSS_KEY_STRUCT_KEY12 |
TSS_KEY_SIZE_2048 |
TSS_KEY_VOLATILE |
TSS_KEY_AUTHORIZATION;
TSS_FLAG binding_key_flags =
TSS_KEY_TYPE_BIND |
TSS_KEY_STRUCT_KEY12 |
TSS_KEY_SIZE_2048 |
TSS_KEY_VOLATILE |
TSS_KEY_AUTHORIZATION;
I do not have access to a real TPM at the moment and I can not verify the code
with the real thing. But I thought I ask first before building the test machine.
Any ideas?
