FPGA software authorization method

Abstract

The invention discloses an FPGA software authorization method, and belongs to the technical field of information transmission and processing. According to the method, an authorization code is formed by utilizing the Device DNA of the FPGA hardware, and the software can continue to work after completing authorization authentication at first in the operation stage, so that the property right of the FPGA software can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of information transmission and processing, in particular to an FPGA software authorization method. Background technique [0002] In general engineering development projects, FPGA hardware boards and burned bit files (compiled and generated by FPGA software) will be delivered to users as deliverables at the same time. Usually, there is no one-to-one correspondence between FPGA hardware boards and bit files. Therefore, after the delivery of the project is completed, there is a possibility that the bit file can be used on other FPGA hardware platforms, and the software cannot be effectively protected. [0003] At present, all FPGA devices of Xlinx have Device DNA, which is a 57-bit binary sequence burned into the chip during device production, and the Device DNA of each chip is unique. Therefore, DeviceDNA can be regarded as the identity of the FPGA device. Using this identity, the FPGA software must first ...
