Embodiment Construction

[0073] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0074] First, divide the subsystems of the trusted cryptographic module, and strictly divide them according to the functions realized by each subsystem, so that the dependence of each partitioned subsystem is low; here, the trusted cryptographic module can be divided into the following subsystems: cryptographic subsystem , TCM management subsystem, platform identity management subsystem, storage protection subsystem, identification and authentication subsystem, integrity protection subsystem, trusted path subsystem.

[0075] The dependencies between the various subsystems are as follows: Figure 8 As shown in , where the arrow points to indicate the dependency relationship, for example, the cryptosystem points to the integrity protection subsystem, indicating that the cryptosystem depends on the integrity protection subsystem.

[0076] Second...

Abstract

The invention discloses a test case generating method and the test system for a credible password module, belonging to the computer technology field. The method in the invention is: modeling inside a subsystem divided by the credible password module, generating the extended finite state machine of the subsystem, then generating the test case through the extended finite state machine; the test system of the invention comprises: a script resolving engine, a result analysis engine, and a communication module. Compared with the existing technology, the test case in the invention can be generated in an automated way, avoided that the integrality of the test in a manual test case can not be confirmed so that the reliability of the test result is not high, and the system in the invention is an automated test system, much manual interpose is reduced, saved the cost.

Description

technical field [0001] The invention relates to a testing method of an embedded system and a system thereof, in particular to a method for generating a test case of a trusted cryptographic module and a testing system thereof, belonging to the technical field of computers. Background technique [0002] Trusted computing platform technology is a new technology to solve security problems through hardware root of trust. Trusted platform module (TPM) is the core and foundation of trusted computing platform, and is the key to the promotion and application of trusted computing platform. The development and application of the trusted computing platform are inseparable from the corresponding technical specifications. In order to promote the development of the trusted computing platform, in 2003, the Trusted Computing Group (TCG) gave the trusted platform module (Trusted PlatformModuel, TPM for short) 1.2 specification defines the functions of TPM in detail. At the same time, in orde...
