Abstract

The invention discloses a trusted platform module aiming at a trusted embedded system. The trusted platform module aiming at the trusted embedded system comprises a tdd1 module, a tpmd module, a tpmd-dev module, a coding and decoding module, a cryptology module, a storage module and an executing engine module. The trusted platform module is provided with seven modules including the tdd1 module, the tpmd module, the tpmd-dev module, the cryptology module, the storage module and the executing engine module, in practical use, the modules are compiled and transplanted into an embedded system platform, no special hardware conditions are required, and the defect that the trusted platform module is hard to expand when a trusted embedded computation platform based on a physical TPM (trusted platform module) is overcome. Every module of the trusted platform module is encoded by software, easiness in realization, modification and expanding is achieved, and the problems of complexity in realization in a hardware manner and difficulty in expanding of the trusted platform module are solved; an entity can access to the trusted platform module in tdd1, tpmd and tpmd-dev manners, the access manners are flexible, and functions of the trusted platform module are easy to test and manage.

Description

technical field [0001] The invention belongs to the technical field of embedded systems, and in particular relates to a trusted platform module for trusted embedded systems. Background technique [0002] When building a trusted embedded system, due to the wide variety of embedded system platforms, there are fewer trusted platform module (TPM) chips for embedded systems, and the lack of a unified interface between the trusted platform module (TPM) and the embedded hardware platform, For several reasons, such as the lack of external interface resources in the existing embedded platforms, it is impossible to find a design method for a trusted embedded system platform based on a Trusted Platform Module (TPM) chip that is relatively easy to implement and has a certain degree of versatility, which hinders trusted Application and popularization of embedded systems. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a trusted ...
