Embodiment Construction

[0039] Since the current Trusted Computing Platform Module TPM specification mainly focuses on architecture and technical descriptions, the functions described therein are inseparable and depend on each other, and some functions must be based on other functions to run. Therefore, for TPM testing, it is first necessary to extract, divide and summarize the trusted functions in the TPM specification.

[0040] The present invention obtains the functional division of the TPM by extracting the TPM specification. At the same time, the minimum function set of TPM is obtained through analysis, and the divided TPM functions can be mapped to different levels of the minimum function set of TPM, so as to obtain the specific functional dependencies, and based on this, a test system is designed to test the TPM, so that it can be efficiently Cover the TPM function to be tested, and perform a specification compliance test on the TPM.

[0041] Specifically, thinking of the present invention is...

Abstract

The invention provides a trusted platform module testing device which comprises a basic information testing system, a cryptographic code service testing system and a trusted service testing system. The basic information testing system is used for testing basic information of different trusted platform modules, and the basic information of the trusted platform module comprises a base attribute testing function and a function coverage rate; the cryptographic code service testing system is used for testing the basic cryptographic code function of the trusted platform module as a security chip, and the basic cryptographic code function comprises a cryptographic algorithm function, a cryptographic key certificate function and a protocol function; the trusted service testing system is used for testing trusted characteristics of the trusted platform module and the trusted characteristics comprise a trusted memory/report and testing function, a credibility degree memory report function, a terminal security service function and remote certificate function; and all the testing systems are installed on a trusted computing system in which the trusted platform module is arranged as a hardware chip. The application of the device can conduct a standard compliance test for the TPM and efficiently cover the trusted functions of the TPM to be tested.

Description

technical field [0001] The invention relates to the technical field of computer information security, in particular to a trusted platform module (TPM) testing device based on function division, which is used for testing different versions of TPMs from different manufacturers. Background technique [0002] Trusted Computing Group (TCG, Trusted Computing Group) is a large organization composed of industrial and academic component providers, software developers, system developers, network and system companies, which is committed to research and development that can be applied to multiple platforms established, publicly available industry norms. [0003] TCG has released several documents and specifications in multiple application fields, the most important specification is the TPM (Trusted Platform Module) specification. There are two versions of the specification on the TPM, 1.1b and 1.2. [0004] Version 1.1b can refer to: [0005] [1] TCPA Main Specification, Version 1.1b...
