Linux with TCPA Integrity Measurement

This paper describes an end-to-end implementation of TCPA (Trusted Computing Platform Alliance) integrity measurement for Linux kernel. Integrity measurement of the kernel is done through a chaining of PCR (Platform Configuration Register) updates during the bootstrap process of the GRUB kernel loader. The measured integrity values can be reported to remote servers by a Java application that uses a digital signature containing the PCR values. As the hardware platform, we used a stock laptop computer (ThinkPad T30) that is TCPA-enabled.
