[Tpm4java-users] Infineon TPM 1.2: demo code won't work

From: Markus <ax...@go...> - 2006-12-11 16:32:29

Hi,

I recompiled my javaddl.dll to match the function names
of the Infineon device driver library
(see Thread: tpm4java: count not init dll code: -2)
and did some testing.

Here are the results:

1) Sha1Sum example by Erik:

0000000000000000000000000000000000000000  c:\test.txt

Test failed, no Exception thrown.

2) Dice example by Erik:

Exception in thread "main" java.lang.RuntimeException:
java.lang.ArrayIndexOutOfBoundsException: 0
	at de.datenzone.tpm4java.TpmRandom.next(TpmRandom.java:50)
	at java.util.Random.nextFloat(Random.java:336)
	at de.datenzone.tpm4java.examples.Dice.main(Dice.java:29)
Caused by: java.lang.ArrayIndexOutOfBoundsException: 0
	at de.datenzone.tpm4java.TpmRandom.next(TpmRandom.java:45)
	... 2 more

BTW I'm using JDK 1.5.0_10.


Please help!

Markus,

there are two things that should be done:

First, please provide the full stack trace of the exception.

Second, please replace line 24 in Dice. Right now this is:
> Random tpmRandom = TssFactory.getHighLevel().getTpmRandom();

The new code will turn debug information on:
> TssLowlevel low = TssFactory.getLowlevel();
> low.setDebug(true);
> Random tpmRandom = new TssHighLevelImpl(low).getTpmRandom();

When running the program, the raw TPM commands and replies will be
printed on stdout. Given these information, I should be able to see
which problem the TPM is having.

Thanks,
Martin

Hi,

I tried several TPM commands but all I got was a 16k array of zeros.

:-(

Is your TPM broken?

Did you try the take ownership command?

Did you try the selftest?

Do you got a vendor library, which is able to execute any command?

Did you enable the tpm in your bios?

I'm using the Infineon Security Platform Software.

It's already activated and initialized. Ownership was taken using the
infineon software. The self-test succeeded. TPM applications like the
Personal Security Drive work fine.

> Do you got a vendor library, which is able to execute any command?

Filemon (sysinternals) doesn't show any access to the infineon tpm
DDL-dll, but to some other infineon dlls. I believe they use their own
dlls for tpm stuff.

Sadly I don't know any non-infineon application to test my tpm with. Do you?

Did you do the self test with tpm4java or with the infinion software?

Well, for Windows, I only know IBM client security and tpm4java.

What environment do you use? I used windows xp sp2 with visual
studio .net 2005. Do you get any compiler warning when compiling your
native code?

I did the self-test with the infineon software.

My environment: Win XP SP2, Visual Studio .NET 2003

Visual Studio .NET Command Prompt:
cl /Wall /I include /I include\win32 /LD javaddl.c
(include contains the jdk 1.5 jni header files)

I attached the compiler output (warnings are only visible when
compiling with /Wall).

Do you know of any other test case which could indentify the cause of
the failure?

As all commands fail, I guess that either this DLL is not really
speaking with your TPM, or maybe the TPM is exclusively used by another
application.

I'm afraid I don't know much that could help you. Is there any other
Infineon related DLL that exports similar functions?
