Problems solved by technology

[0007] However, the BIOS of existing computers is injected with plaintext One Number, or plaintext SN (SerialNumber, identification number), which is easy to be compared and cracked, easily tampered with, easy to be copied, and easy to be forged
It will cause hackers to steal legitimate user resources
[0008] Moreover, the content server’s judgment on the user’s platform is only based on the plain text One Number or SN, which has low security
Similarly, the computer has no hardware-based anti-phishing means, cannot identify fake content servers, and only implements simple one-way authentication

Embodiment Construction

[0042] The invention provides a two-way hardware authentication method and system for realizing two-way authentication between a content server and a computer.

[0043] see figure 1 , which is a flow chart of the first embodiment of the two-way hardware authentication method of the present invention.

[0044] The two-way hardware authentication method described in the first embodiment of the present invention includes the following steps:

[0045] S100. Send the encrypted result of the user identification number generated by the production server in the production stage to the computer, and store the encrypted result as the computer identification number in the BIOS data block.

[0046] The computer identification number may be encrypted by the content server and stored in the BIOS data block.

[0047] In the production stage, the production server will first generate a USER (user) SN (for example: NA0608XXXXXX), which will be printed and pasted on the outside of the compute...

Abstract

The invention relates a method for authenticating two-way hardware. The method comprises the following steps of: storing a computer mark number, a platform fingerprint, a platform fingerprint production certificate signature, and an address of a content server in a data block of a basic input / output system; extracting the address of the content server in the data block of the basic input / output system, and sending the address to a computer; building a connection between the computer and the content server according to the address of the content server; extracting a computer platform fingerprint, and verifying that the computer platform fingerprint is consistent with the platform fingerprint stored in the data block of the basic input / output system; and submitting the platform fingerprint production certificate signature to the content server to verify a production certificate; confirming that the data block of the basic input / output system is legal after passing the verification; sending a verification result of the content server to the computer through the service certificate signature; and confirming that the content server is legal after the computer passes the service certificate verification in the data block of the basic input / output system. The method and system for authenticating the two-way hardware realize two-way authentication between the content server and the computer.

Description

technical field [0001] The invention relates to an authentication method, in particular to a bidirectional hardware authentication method and system based on a basic input and output system. Background technique [0002] Existing computers will be written with specific information during the production stage as the unique identifier of the computer. The specific information written is not easy to be tampered with, copied and attacked. [0003] Generally, the computer manufacturer is provided with a server. When the user's computer is turned on and goes online, the server can immediately identify the computer because the computer has the unique identifier. The computing interface can download specific service content through the server. [0004] In fact, the relationship between the computer and the server that produces the computer is similar to the "Shenzhouxing" type of PC online identification requirements. That is, without user intervention, the computer can be automa...
