All Implemented Interfaces:

TcIStreamDest

public class TcTddlLinux
extends TcTddl

This class implements the TDDL layer for LINUX operating systems. The basic assumption is that the TPM is made available by means of a character device (e.g. /dev/tpm0).

Method Detail

open

public void open()
          throws TcTddlException

This method opens the TPM device. I tries to open predefined device file names one after the other until a device file could be opened for read/write access.

Specified by:

open in class TcTddl

Throws:

TcTddlException - This exception is thrown if no TPM device could not be opened.

isOpen

public boolean isOpen()

This method returns true if the TPM device is already open, false otherwise.

Specified by:

isOpen in class TcTddl

close

public void close()
           throws TcTddlException

This method closes the previously opened TPM device.

Specified by:

close in class TcTddl

Throws:

TcTddlException

transmitData

public TcBlobData transmitData(TcBlobData command)
                        throws TcTddlException

This sends the given byte blob to the TPM.

Parameters:

command - The command blob to the sent to the TPM.

Throws:

TcTddlException - This exception is thrown if writing to or reading from the TPM device failed.
