This standard specifies the composition and interface standards of the TCM service module, including TSP, TCS, TDDL, which are TCM application layer- faced interface standards. This standard applies to the development of TCM-based application.2 Normative references
The following documents are essential to the application of this document. For the dated documents, only the versions with the dates indicated are applicable to this document; for the undated documents, only the latest version (including all the amendments) are applicable to this standard. GB/T 32905-2016 Information security technology SM3 cryptographic hash algorithm3 Terms and definitions
The following terms and definitions apply to this document. The master key used to protect the platform identity key and user key, which is an implementation of the trusted storage root. A support system built into a computing system for implementing trusted computing functions.4 Abbreviations
The following abbreviations apply to this document.5 Software architecture
The software architecture of the TCM service module is as shown in Figure 1. This standard makes explanation using the C language as an example to compile relevant functions and interfaces.6 TCM application service
Work objects can be subdivided into authorized work objects and unauthorized work objects. Unauthorized work objects include PCR composite objects and hash objects, as shown in Figure 2.Authorized objects include TCM objects, key objects, NV storage objects, migration data objects, encrypted data objects, as shown in Figure 3.7 TCM core services
Obtain event information of the specified PCR in the PCR event manager in the TCS. It returns the specified PCR event information if pNumber has a specific value. If it is NULL, it returns all event information of the specified PCR. Obtain the PCR event information of the specified PCR from the start of the specified event.8 TDDL device driver library
Table 26 lists the error codes that appear in TDDL. In addition, the error code associated with it is listed in each Tddli function definition (specific values can be defined by the manufacturer). This function directly passes the TCM command to the TCM device driver, so that the TCM completes the corresponding operation. It also provides a channel for the TCM parameters. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
