Hello, I have an amd64 ubuntu 16.04 machine with hardware TPM. I'm very new to TPM and all related libraries and services.
I tried to run testsuite after downloading trousers from https://launchpad.net/ubuntu/xenial/amd64/trousers/0.3.13-4 Then I noticed that a bunch of results would get TPM_E_DEFEND_LOCK_RUNNING, which is the code for this error: "TPM is defending against dictionary attacks and is in some time-out period." I have taken the ownership with tpm_takeownership and then specified the owner and srk secrets in tcg/include/common.h. I also tried the following: export TESTSUITE_OWNER_SECRET="my owner secret" export TESTSUITE_SRK_SECRET="my srk secret" But I'm getting the same result. The test that I would like to get a successful result is Tspi_TPM_CreateIdentity. One more thing: after installing trousers and ownership has been taken, I tried to run tpm_getpubek and now it's showing me this error message: Tspi_TPM_GetPubEndorsementKey failed: 0x00000008 - layer=tpm, code=0008 (8), The TPM target command has been disabled then, Tspi_TPM_GetPubEndorsementKey failed: 0x00000803 - layer=tpm, code=0803 (2051), TPM is defending against dictionary attacks and is in some time-out period Could someone guide me on how I could solve this issue? I don't have Windows running on my machine. I would like to use TPM in the Linux directly. Thank you in advance to all of you out there.
