Embodiment Construction

[0075] The distributed system involved in the embodiment of this application may mainly include the following two situations:

[0076] (1), a single physical device itself is a distributed structure, see figure 1 , the physical device may include a main control board and at least one line card. In addition, the physical device may also include at least one standby main control board. The main control board and the standby main control board can be used to manage and control line cards for data processing.

[0077] (2), multiple physical devices constitute a distributed system, see figure 2 , the system may include at least one master device and at least one controlled device, the master device is used to manage and control the controlled device.

[0078] The distributed system in the embodiment of the present invention may include a plurality of processing units, and each processing unit may have an independent Basic Input Output System (BIOS for short) file and an indepen...

Abstract

The embodiment of the invention provides a method, devices and a system of deployment of a trusted platform module (TPM), and relates to the field of communications technology. The method, device, and system are used to deploy the TPM in the distributed system to enable a processing unit, on which the hardware TPM is not deployed, in the distributed system to use a resource of the deployed hardware TPM to carry out security protection, and improve the system security. A specific solution is: acquiring a resource reference identifier of the hardware TPM of a first main processing unit by the first sub processing unit, and sending a hardware TPM resource acquisition message to the first main processing unit, wherein the hardware TPM resource acquisition message includes the resource reference identifier. receiving the hardware TPM resource acquisition message, which is sent by the first sub processing unit, by the first main processing unit, and providing the resource of the hardware TPM to the first sub processing unit according to the hardware TPM resource acquisition message; and utilizing the resource of the hardware TPM of the first main processing unit by the first sub processing unit to execute a trusted function.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a trusted platform module (Trusted Platform Module, TPM for short) deployment method, device and system. Background technique [0002] A distributed system is a network system composed of multiple interconnected processing units with independent data processing capabilities. These processing units can be geographically adjacent or dispersed, and each processing unit is managed in a global manner. The resources in the network can be allocated dynamically, and all processing units can be controlled to work together, which can enhance the scalability, stability and execution efficiency of the network system. [0003] In order to ensure the security of the distributed system, the existing technology deploys a TPM security chip, that is, a hardware TPM, on each processing unit in the distributed system, so as to use the resources such as keys and com...
