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. -
Trusted System Concepts
Trusted System Concepts Trusted System Concepts Marshall D. Abrams, Ph.D. Michael V. Joyce The MITRE Corporation 7525 Colshire Drive McLean, VA 22102 703-883-6938 [email protected] This is the first of three related papers exploring how contemporary computer architecture affects security. Key issues in this changing environment, such as distributed systems and the need to support multiple access control policies, necessitates a generalization of the Trusted Computing Base paradigm. This paper develops a conceptual framework with which to address the implications of the growing reliance on Policy-Enforcing Applications in distributed environments. 1 INTRODUCTION A significant evolution in computer software architecture has taken place over the last quarter century. The centralized time-sharing systems of the 1970s and early 1980s are rapidly being superseded by the distributed architectures of the 1990s. As an integral part of the architecture evolution, the composition of the system access control policy has changed. Instead of a single policy, the system access control policy is more likely to be a composite of several constituent policies implemented in applications that create objects and enforce their own unique access control policies. This paper first provides a survey that explains how the security community developed the accepted concepts and criteria that addressed the time-shared architectures. Second, the paper focuses on the changes currently ongoing, providing insight into the driving forces and probable directions. This paper presents contemporary thinking; it summarizes and generalizes vertical and horizontal extensions to the Trusted Computing Base (TCB) concept. While attempting to be logical and rigorous, formalism is avoided. This paper was first published in Computers & Security, Vol. -

TRUSTED COMPUTING GROUP (TCG) TIMELINE February 2011
TRUSTED COMPUTING GROUP (TCG) TIMELINE February 2011 2003 Trusted Computing Group is announced with membership of 14 companies, including Promoters and board members AMD, Hewlett-Packard, IBM, Intel Corporation, Microsoft, Sony Corporation and Sun Microsystems, Inc. TCG structure and vision are created to enable extension of trusted computing beyond the PC into the enterprise. TCG adopts existing specifications for the Trusted Platform Module (TPM) security chip for clients and publishes as an open industry specification. 2004 TCG announces the Trusted Platform Module (TPM) specification 1.2. Manufacturers begin shipping a variety of enterprise desktop and notebook PCs equipped with TPMs and software to enable applications including data and file encryption, secure email, single sign-on, storage of certificates and passwords and other applications. Members begin participating in work groups to address security in mobile devices, storage, servers, peripherals and infrastructure requirements. TCG also announces the Trusted Network Connect (TNC) subgroup to work on an open specification for network access control and endpoint integrity and the addition of almost 30 new members to focus on the effort. Group starts to define requirements and use cases for an open specification. Membership expands to 98 companies by end of the year, with participation broadening beyond semiconductor and client companies to software developers, networking and storage companies. The group initiates an advisory council of leading IT, privacy, finance and security industry experts. The group also begins a liaison program with other industry standards groups and begins a mentoring program for those researchers and academic institutions doing research on trusted computing and related topics. 2005 The group expands its board of directors. -

A special thank to Jonas Stewén, employee at AerotechTelub, for his help with material and his opinions on our work. We also want to thank Ola Flygt our supervisor and Mathias Hedenborg our examiner at Växjö University. Växjö, June 2004 Abstract Trusted Computing Platform Alliance (TCPA), now known as Trusted Computing Group (TCG), is a trusted computing initiative created by IBM, Microsoft, HP, Compaq, Intel and several other smaller companies. Their goal is to create a secure trusted platform with help of new hardware and software. TCG have developed a new chip, the Trusted Platform Module (TPM) that is the core of this initiative, which is attached to the motherboard. An analysis is made on the TCG’s specifications and a summary is written of the different parts and functionalities implemented by this group. Microsoft is in the development stage for an operating system that can make use of TCG’s TPM and other new hardware. This initiative of the operating system is called NGSCB (Next Generation Secure Computing Base) former known as Palladium. -
Expanding Malware Defense by Securing Software Installations*
Expanding Malware Defense by Securing Software Installations? Weiqing Sun1, R. Sekar1, Zhenkai Liang2 and V.N. Venkatakrishnan3 1 Department of Computer Science, Stony Brook University 2 Department of Computer Science, Carnegie Mellon University 3 Department of Computer Science, University of Illinois, Chicago. Abstract. Software installation provides an attractive entry vector for malware: since installations are performed with administrator privileges, malware can easily get the en- hanced level of access needed to install backdoors, spyware, rootkits, or “bot” software, and to hide these installations from users. Previous research has been focused mainly on securing the execution phase of untrusted software, while largely ignoring the safety of installations. Even security-enhanced operating systems such as SELinux and Vista don't usually impose restrictions during software installs, expecting the system administrator to “know what she is doing.” This paper addresses this “gap in armor” by securing software installations. Our technique can support a diversity of package managers and software installers. It is based on a framework that simplifies the development and enforcement of policies that govern safety of installations. We present a simple policy that can be used to prevent untrusted software from modifying any of the files used by benign software packages, thus blocking the most common mechanism used by malware to ensure that it is run automatically after each system reboot. While the scope of our technique is limited to the installation phase, it can be easily combined with approaches for secure execution, e.g., by ensuring that all future runs of an untrusted package will take place within an administrator-specified sandbox.
