[GB/T 29829-2013, definition 3.1.13]4 AbbreviationsFor the purpose of this document, the following abbreviations apply. BIOS: Basic Input Output System CRTM: Core Root of Trust for Measurement TCM: Trusted Cryptography Module TPCM: Trusted Platform Control Module TPM: Trusted Platform Module TSB: Trusted Software Base TSM: TCM Service Module TSS: TCG Software Stack5 Architecture of trusted computingTrusted computing refers to the safety protection while computing, and the whole computing process can be measured and controlled without interference, so that the computing results are always consistent with expectations. The trusted computing system is composed of trusted computing nodes and trusted connections between them, which provide corresponding levels of security for the network environment in which they are located, as shown in Figure 1. According to the functions of the nodes in the network environment, trusted computing nodes can deploy applications with different functions according to their business environment. Trusted computing nodes include trusted independent module or physical package, or be realized by integration and virtualization with TCM/TPM through IP core or firmware. 6.1.3 Trusted main board Trusted main board is a computer main board integrated with TPCM, which uses TPCM as a root of trust to establish a chain of trust and provides the connection between TPCM and other hardware. The composition structure and function interfaces of trusted main board shall comply with GB/T 29827-2013. 6.1.4 Trusted software base Trusted software base (TSB) implements monitoring and measurement of applications running in the host basic software. The composition structure and function interfaces of TSB shall comply with GB/T 37935-2019. 6.1.5 Trusted connection Trusted connection realizes the identity authentication and platform authentication of trusted computing nodes when they access the network, including user identity authentication, platform identity authentication, and platform integrity assessment, ensuring that only trusted computing nodes can access the network. The specific structure and function interfaces of trusted connection shall comply with GB/T 29828-2013. 6.2 Integrity measurement modes 6.2.1 Arbitration measurement mode The arbitration measurement mode of trusted components is shown in Figure 3. The participating components shall include TCM/TPM, TPCM, trusted main board and TSB. At the hardware and firmware layer, TPCM shall be the first running component of the trusted computing node. As the root of trust of the trusted computing node, it shall apply TCM/TPM or other cryptographic algorithms and integrity measurement functions to actively initiate integrity measurement operations on computing components such as BIOS and host basic software, and actively arbitrate and control based on the measurement results. At the host basic software and middleware layer, TPCM provides support for ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
