marking the machine code to be authorized and the corresponding two-dimensional code on the corresponding hardware body;
and scanning the machine code two-dimensional code on the hardware body through code scanning equipment to acquire machine code information.
According to one embodiment of the invention, when the Haisi HI3559AV100 development board is produced, a machine code is formed by adopting a mode of production date, a board serial number and a board model, and the machine code is printed and pasted on a specified position of an opening board or is marked on the development board through an etching technology. Referring to fig. 3, the machine code of the haisi development board is scanned to 2019120008NLE-AI800, and the 8 th development board produced in 12 months in 2019 can be determined, and the model of the board product is NLE-AI 800.
Specifically, the invention provides an embodiment, a server pre-codes all hardware which is expected to be produced on the same day according to a production plan on the same day according to a sequence number rule, stores the hardware in the server and forms a pre-distribution machine code list, namely a machine code list to be authorized, and simultaneously stores machine code information in the list into a two-dimensional code form; after the hardware is produced, machine code plaintext information and two-dimensional code information are marked at the designated position of the hardware according to the serial number, the plaintext information is convenient for reading out production information, model information and the like of the hardware, and the two-dimensional code information can be conveniently identified and read by code scanning equipment.
After production is completed, hardware testing is carried out, a code scanning gun interface is reserved on the development board, a code scanning gun is connected, and two-dimensional codes on the development board are scanned and read to machine codes.
S12: and sending the machine code to a server for verification, specifically: the server compares the machine code with a pre-stored list of machine codes to be authorized, if the machine code is in the list to be authorized, the machine code passes verification, in one embodiment, the machine code passing verification can be identified as a verified state; indicating that the number on the hardware body is a legitimate machine code for the batch and that the machine code has not been repeatedly verified. Therefore, the authorization condition of hardware can be managed on the server, for example, the authorization quantity can be checked, on the other hand, the tested development board can execute the verification step, and according to the list to be authorized, whether the condition of device missing test exists in the test stage can be checked to prevent the condition of missing test.
S13: after the machine code passes verification, the server encrypts the machine code to form an encrypted character string and sends the encrypted character string to hardware;
s14: the hardware stores the received encryption character string in otp storage space of the hardware;
in the embodiment of the invention, the hardware is a Hai Si development board, the CPU of the development board contains an OTP (one Timer programmable) storage space, and the storage space is characterized in that the storage space is operated by a specific register, and cannot be erased after being written once, namely, the space address can be written once, and the subsequent writing cannot be repeated, but the reading operation can be repeated.
The tested hardware can be put into use, and the hardware using step comprises the following steps:
s21: the information in the storage space of the hardware otp is read, the encrypted character string information in the storage space of the hardware otp is decrypted by software embedded in the hardware, and if the decrypted information is a legal machine code, the hardware is judged to be authorized, and the software function on the hardware is allowed to be used by the hardware.
If otp there is no content in the storage space, the hardware is determined to have not been production tested. Under the condition, if the batch is not tested, the hardware of one batch can be traced back through the machine code on the hardware, so that the subsequent product recall is facilitated.
In an embodiment of the present invention, the software decrypts the encrypted character string, and if the decrypted machine code is information that meets a preset encoding rule, that is, the mode of the production date + the board serial number + the board model in the above embodiment, it is determined that the machine code is a legal machine code, and the software is allowed to run on the hardware.
In the embodiment of the invention, the encryption rule of the machine code by the server side is matched with the decryption rule of the software pair otp space information, so that the device side can restore the machine code plaintext. One way of implementation is as follows: the decryption program is called for the application program in a static library mode, when the algorithm or software of the application program on the development board needs to be used, the decryption program calls the static library to decrypt the information of the opt storage space, and if no information exists in the otp storage space or the stored machine code is not legal, the decrypted code may be a pile of messy codes. This situation indicates that the development board hardware does not match the software on the development board, and may be that the hardware is replaced, not factory-owned, or that the software is not originally installed and cannot be authorized to succeed.
The authorization of the hardware usage steps described above may be performed in an offline state.
