Method Detail

localTpmSimulator

public static Tpm localTpmSimulator()

Connect to a simulator running on localhost using the default ports. Upon successful connection this method power-cycles the simulator and executes TPM2_Statup(SU_CLEAR) command. Note that only one Tpm device instance at a time can connect to a local simulator.

Returns:

New Tpm instance with an connected TpmDeviceTcp

remoteTpm

public static Tpm remoteTpm(String hostName,
                            int port)

Connect either to a TPM simulator or to a proxy server implementing the TPM simulator protocol. The latter can be used to access platform TPM on a remote host.

Parameters:

hostName - Remote host (dotted IP address or DNS host name)

port - Port number of the TPM command socket. Note that the protocol also uses port+1 to accept control signals.

Returns:

New Tpm instance with an connected TpmDeviceTcp

platformTpm

public static Tpm platformTpm()

Connect to the platform TPM device. On Windows this will connect via TPM Base Services (TBS). On Linux this will connect to /dev/tpm.

Returns:

The new Tpm instance with an connected TpmDeviceTbs
