Hi Group,
I happend to get access to an HP machine featuring a Broadcom 1.2 TPM. Just
out of curiosity i gave jTSS (not the wrapper) a try on this machine. I
thought that it might be a good idea to share my experiences:
- a manual TPM_Startup was required (not a problem of the TPM but most likely
of the BIOS)
- Broadcom TPMs really do come without EK. That means that it is up to the
user to trigger EK creation. Luckily jTSS does support that out of the box
(using TciTpm.createEndorsementKey). Calling that function worked as expected
and an EK was created.
- Subsequent TPM ownership command worked without problems
- Boradcom TPMs are not all that fast: running the test suite as shipped with
jTSS 0.1 took about 660 seconds
- all test cases completed successfully
All in all pretty nice result meaning that one more TPM can be added to the
list of supported TPMs.
Bye,
