Trusted Platforms UEFI, PI and TCG-Based Firmware
White Paper by Intel Corporation and IBM Corporation Trusted Platforms UEFI, PI and TCG-based firmware Vincent J. Zimmer Intel Corporation Shiva R. Dasari Sean P. Brogan IBM September 2009 Executive Summary This document provides an overview of the interactions of the Trusted Computing Group (TCG) [TCG Overview], the firmware standards work within the Unified Extensible Firmware Interface (UEFI) Forum, and implementation practices of UEFI PI-based [UEFI Book][UEFI Shell Book][UEFI Overview] implementations. In addition, this paper will provide some use-cases and implementation examples of this technology in addition to the industry threats that motivate the design of this class of technology. This paper is mainly intended for Hardware, firmware, software, and BIOS engineers. But beyond this audience, some of the information in this paper will be valuable for IT decision makers, marketing, and other parties. The goal of the paper is to take away an understanding of the motivations behind trusted platform design, the terminology of trust, how to navigate the Trusted Computing Group set of specifications and technology that relate to platform, impact on platform firmware and UEFI, instances of deployment in the market, and some future possible directions for hardware and firmware. ii Table of Contents Overview ............................................................................................................2 Problems to solve ...........................................................................................3 Security architecture -
Open Source TPM Support
Open Source TPM support Open source application and support software for TPM is available for several operating systems like Linux, Android and in different programming languages supporting the following scenarios: - embedded Systems - servers - mobile communication and portable devices (e.g. tablet computer or smartphone) Open source implementations can also be ported to other platforms and processors and may be act as a starting point for the development of new applications. Some open source projects from the following list are supported by Infineon while other packages are separately developed by independent parties. The following list of Open Source software utilizing Trusted Computing and/or TPM software makes no claim to be complete and represents a limited number of projects: 1. Linux TPM Driver ( http://www.kernel.org ) Linux device driver for Trusted Platform Modules (TPM) in standard kernel (Vanilla). 2. I2C driver for TPM The driver is available on Linux kernel.org ( https://lkml.org/lkml/2011/7/22/137 ) 3. Trusted GRUB ( http://sourceforge.net/projects/trustedgrub ) Trusted GRUB extends the GRUB bootloader for Linux platforms with TPM support. This makes it possible to provide a secure Bootstrap architecture; Code is in general useful for initializing a Trusted Platform Module and execute integrity measurement based on Trusted Computing. 4. UBoot based on TPM with I2C ( http://git.chromium.org/gitweb/?p=chromiumos/third_party/u- boot.git;a=tree;f=drivers/tpm/slb9635_i2c;hb=chromeos-v2011.03 ) UBoot involving TPM using I2C interface. 5. The TROUSERS project ( http://sourceforge.net/projects/trousers ): An open-source TCG Software Stack implementation created and released by IBM. -

Recipe for Mobile Data Security: TPM, Bitlocker, Windows Vista and Active Directory
Recipe for Mobile Data Security: TPM, Bitlocker, Windows Vista and Active Directory Tom Olzak October 2007 If your business is like mine, laptops regularly disappear. Until recently, centrally managed mobile storage encryption solutions for Windows environments were either too costly, required users to carry a key-resident device, or relied on keys residing on local disk. Sometimes the best solution under these circumstances was the presence of administrative controls (i.e. policies) prohibiting users from storing sensitive information on local laptop drives. With the proliferation of TPM 1.2 across most laptop platforms and the release of Microsoft Windows Vista, most roadblocks to laptop data encryption have been removed. In this paper, I explore the challenges facing security managers responsible for laptop data security, TPM technology, and how the features of a TPM can integrate with Microsoft’s Bitlocker and Active Directory technologies to provide for more secure data on the road. The Challenges Vulnerable Laptop Data When a mobile user’s laptop is stolen, a variety of data might be potentially exposed. The following is a short list of some of the most common types of sensitive information that might be found on a laptop drive: ¾ ePHI – Electronic Protected Health Information, protected under the HIPAA, is any information that can be used to uniquely identify a health care recipient. ¾ PII – Essentially, Personally Identifiable Information is any data that can be used to steal a person’s identity. Most states have passed laws requiring businesses to take steps to protect this information as well as to notify and assist victims if this information is compromised. -
Attestation and Trusted Computing
Attestation and Trusted Computing Abstract A look at the cryptographic techniques and protocols used in trusted computing with particular attention to remote attestation. CSEP 590: Practical Aspects of Modern Cryptography March 2006 J. Christopher Bare Introduction Trusted computing, in some form, is almost certain to become part of the computing landscape over the next few years. This is because email viruses, trojans, spyware, phishing scams, key-stroke loggers, and security exploits are so much a part of the landscape already. The current computing infrastructure was built with a premium on openness and interoperability which has paid huge dividends in terms of creativity and innovation. But, the same openness is somewhat problematic for security. Experience has shown that the access control model of present operating systems is inadequate against many types of attacks particularly in the hands of inexpert users. Previous attempts to roll out cryptographic infrastructure to a mass-market have met with limited success.[10] The various competing visions of trusted computing seek to strike a workable balance between enhanced security and openness and backward-compatibility. One component of trusted computing that has attracted particular attention is remote attestation. Attestation allows a program to authenticate itself and remote attestation is a means for one system to make reliable statements about the software it is running to another system. The remote party can then make authorization decisions based on that information. This paper will look at the cryptographic techniques and protocols used in trusted computing with particular attention to remote attestation. Trusted Computing The term trusted computing applies to a number of distinct proposals and initiatives with the general goal of engineering more security into commodity computing systems. -
