IBM TPM Emulator Fork

A fork of the IBM software TPM code from http://sourceforge.net/projects/ibmswtpm/

Specifically, this is a fork of revision 4720 https://sourceforge.net/projects/ibmswtpm/files/tpm4720.tar.gz/download

It includes patches and bug fixes required to use the libtpm utilities with keylime: https://github.com/mit-ll/python-keylime

To build the libtpm utilities for use with keylime. First get prerequisites:

On Ubuntu: apt-get -y install build-essential libssl-dev libtool automake

On Centos: yum install -y openssl-devel libtool gcc automake

then build and install with:

cd tpm4720/libtpm
./comp-chardev.sh
sudo make install

Build for use with keylime with the TPM emulator

Building on ubuntu/debian

cd tpm4720/scripts

./install.sh

Building on centos

cd tpm4720/scripts

./install-centos.sh

Building on a mac

you need brew installed prior to running this

cd tpm4720/scripts

./install-mac.sh

Using the emulator

The above install scripts will also install some helpful scripts for starting and resetting the emulator.

To reset the TPM emulator, use:

These scripts store state in in the user's home directory ~/.tpm0
