Embodiment 1

[0023] The first embodiment provides a trusted computing trust root device for computers, which is applied to ordinary computers to enable ordinary computers to have trusted computing functions, such as figure 1 As shown, the trusted computing trust root device includes:

[0024] circuit board 1, interface conversion module 3 and at least one root of trust module 4;

[0025] Wherein, the circuit board 1 is provided with an interface 2, and the interface 2 can adopt a PCI interface or a PCI-E interface or a USB interface, which is connected to the PCI interface or PCI-E interface of the computer motherboard (that is, the PCI slot on the computer motherboard or the PCI-E interface). PCI-E slot) or USB interface; when interface 2 adopts PCI interface or PCI-E interface, it is generally the PCI interface or PCI-E interface formed by the electrical connection between the interface module and the golden fingers printed on the circuit board. The golden finger on the circuit board re...

Embodiment 2

[0033] The second embodiment provides a trusted computing root of trust device for computers, which is applied to an ordinary computer to enable the ordinary computer to have a trusted computing function. The structure of the root of trust device is basically the same as the root of trust device given in the first embodiment above. The same, the difference is that the root of trust device in this embodiment is also provided with an identity recognition module 5 and a main control module 6, such as image 3 As shown, the identity recognition module 5 and the main control module 6 of the root of trust device are both arranged on the circuit board 1, the identity recognition module 5 and the main control module 6 are respectively electrically connected with the interface conversion module 3, and the main control module 6 is respectively connected with the identity Identification module 5. Each root of trust module is electrically connected;

Abstract

The embodiment of the invention provides a trusted computation trust root device for a computer and the computer. The device comprises a circuit board, an interface conversion module and at least one trust root module, wherein the circuit board is connected with an interface, the interface is matched with a PCI (Programmable Communication Interface), a PCI-E interface or a USB interface of a computer motherboard, the interface conversion module and the trust root module are both arranged on the circuit board, the interface conversion module is used for exchanging data between the interface of the circuit board and the PCI interface, the PCI-E interface or the USB interface of the computer, and the trust root module is used for carrying out secret key production and encryption and decryption treatment, storing a secret key and sensitive data and supplying integrity measurement, data safety protection and identity authentication information. The device can be used for an ordinary computer to enable the ordinary computer to have the safety of a trusted computer.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a trusted computing trust root device for computers and a computer. Background technique [0002] Traditional security means are often concentrated at the network boundary, which is a misunderstanding of people's treatment of information security. In fact, endpoints are where important data is created and stored, and the vast majority of attacks originate from endpoints. Investigating the root cause, security problems are mainly caused by the insecurity of the terminal architecture and operating system. For example, resources may be used arbitrarily, especially the executable code can be modified, and malicious programs can be implanted into attack programs. What is serious is that there is no strict access control for legitimate users, and access beyond the authority can be performed, resulting in unsafe incidents. Traditional security methods overemphasize ease of use, whil...
