Problems solved by technology

However, most of the current trusted startup methods do not verify the security of the TPCM chip itself. Once the TPCM chip is tampered with, it will cause the entire system to lose trust and cannot guarantee the security of the computing environment.

Embodiment 1

[0047] The invention performs reverse identity authentication on the TPCM chip after the boot program is started, supervises the trust root, and ensures the authenticity and credibility of the TPCM chip. Using the memory chip FLASH ID as a third-party trusted factor removes the public factor in identity authentication and prevents the public factor from being stolen or tampered with during the interaction. Realize the credible verification of the source of the trusted chain to ensure the security of the device operating environment.

[0048] Those skilled in the art should understand that the embodiments of the present application may be provided as methods, systems, or computer program products. Accordingly, the present application may take the form of an entirely hardware embodiment, an entirely software embodiment, or an embodiment combining software and hardware aspects. Furthermore, the present application may take the form of a computer program product embodied on one o...

Abstract

The invention discloses a bidirectional authentication trusted starting system and method based on a TPCM chip. A main SPI interface of a TPCM chip is connected with a slave SPI interface of a FLASH storage chip, a slave SPI interface of the TPCM chip is connected with a main SPI interface of a CPU chip, and the main SPI interface of the CPU chip is connected with the slave SPI interface of the FLASH storage chip; a GPIO output pin of the TPCM chip is connected with a RESET reset pin of the CPU chip and is used for realizing starting control on the CPU chip; a STATE pin of the TPCM chip is connected with a GPIO pin of the CPU chip and is used for informing the CPU of whether the measurement process is finished or not and informing whether the TPCM is in an SPI master mode or an SPI slave mode. According to the invention, all authentication information is prevented from being held by the same party in the identity authentication process, so that the security verification of a TPCM chip is realized, and the security of an equipment operation environment is ensured from sources.

Description

technical field [0001] The invention relates to a two-way authentication trusted startup system and method based on a TPCM chip, belonging to the technical field of computer security. Background technique [0002] The trusted computing architecture builds an actual and effective hardware root of trust in the system, and establishes a chain of trust starting from the root of trust through layer-by-layer trust expansion, and finally realizes the trust of the system operating environment. The root of trust is assumed to be unconditionally trusted, and the system does not detect the behavior of the root of trust. Therefore, whether the root of trust is really trustworthy and whether the root of trust will be tampered with by attackers is the key to confirming the credibility of the system. [0003] Trusted Platform Control Module (hereinafter referred to as TPCM) is the root of trust of the active immune trust system, the source of trust of the system, and the basis for the est...
