Abstract

The invention provides a trusted computing system and method based on a trusted computing environment, and the system comprises a trusted hardware layer which comprises a CPU and an RPMB secure storage area; the TEE environment comprises a Trusted OS layer and a trusted root TA layer; the secure communication layer is used for realizing state switching and data exchange between the REE environment and the TEE environment through a secure message instruction provided by the CPU; the REE environment comprises a trusted firmware UEFI-BIOS module, a trusted bootstrap program Trusted Grub module, a trusted kernel Trusted Kernel module and a trusted client module from bottom to top; each module in the REE comprises a trusted base; and the application layer comprises various business applications. According to the trusted computing system and method based on the trusted computing environment, the production and manufacturing cost of a host can be saved, the physical structure of the system is simplified, the operational capability and the communication rate are improved, and maintenance and upgrading are facilitated.

Description

technical field [0001] The invention relates to the technical field of trusted computing, in particular to a trusted computing system and method based on a trusted computing environment. Background technique [0002] Information security has four levels: equipment security, data security, content security, and behavioral security. Behavioral security includes: behavioral confidentiality, behavioral integrity, and behavioral authenticity. Trusted computing is an important component of behavioral security. The early research on trusted computing was mainly organized by TCG (International Trusted Computing Working Group). The domestic research on trusted computing basically follows the pace of TCG. [0003] The core of trusted computing research is the TPM hardware chip. The chips of most manufacturers use the classic TPM 1.2 specification as the standard. This specification has been upgraded to TPM 2.0, also known as "Trusted Platform Module Library Specification", which curre...
