  abstract = {
    This paper reports on our ongoing project to use TCPA to transform a
    desktop Linux machine into a virtual secure coprocessor: more powerful
    but less secure than higher-end devices.  We use TCPA hardware and
    modified boot loaders to protect fairly static components, such as a
    trusted kernel; we use an enforcer module---configured as Linux
    Security Module---to protected more dynamic system components; we use
    an encrypted loopback filesystem to protect highly dynamic components.
      All our code is open source and available under GPL from
    http://enforcer.sourceforge.net/
