The Infrastructure Work Group works on the adoption and integration of TCG platform specific specifications into Internet and enterprise infrastructure technologies to enable various business models in a mixed environment of open platform architectures. Conventions for representing and exchanging information useful in making trust decisions are being established by leveraging existing Internet and related infrastructure standards. Considerations are made for representing platform roots of trust, trust chaining, key lifecycle services and the relationship these may have to owner policies. The work group aims to define an architectural framework, interfaces and metadata necessary to bridge infrastructure gaps.
The purpose of this document is to collect, in one document, definitions for three of the abstract credential types identified in the v1.1b TCPA Main specification. These are the Endorsement Key (EK) Credential, the Attestation Identity Key (AIK) Credential, and the Platform Endorsement (Platform) Credential.
This specification describes methods for Endorsement Key (EK) Credential and Platform Credential enrollment.
This specification builds upon the existing IWG work defining Platform Trust Service (PTS) that is capable of creating attestation evidence describing the security state of the system in response to a challenge by a challenger.
Architects, designers, developers and technologists who are interested in the development, deployment and interoperation of trusted systems may find this document helpful in providing both abstract and implementation-specific insights for achieving interoperation between TCG-based systems. But in particular, architects and developers of TPM-related enrollment infrastructure solutions will find this document highly relevant.
The following Infrastructure Work Group specifications have been posted for Public Review: TCG Attestation PTS Protocol: Binding to TNC IF-M, Version 1.0, Revision 25; TCG IWG Reference Manifest (RM) Schema Specification, Version 2.0, Revision 0.2; TCG IWG Core Integrity Schema Specification, Version 2.0, Revision 0.1; TCG IWG Integrity Report Schema, Version 2.0, Revision 0.1
This Architectural Overview provides an introduction to TCG goals and architecture. It defines anticipated scenarios for use of TPM enabled platforms, compliance procedures and anticipated implications on manufacturing and support processes. Anyone looking for an overview of TCG specification and its implications should read this document.
This specification is integral to the TCG Infrastructure Working Group’s (IWG) reference architecture, and is directly related to the TCG’s Integrity Management Model. Specifically, the Security Qualities XML schema defines the structure with which claims about the security provided by a system can be asserted to other parties (e.g. relying parties.)
