Embedded software anti-cloning method
The invention relates to an embedded software anti-cloning method. The method comprises the steps that the FPGA calculates a first authentication secret key according to a preset root secret key and a DNA serial number; when the embedded system initiates authentication, the FPGA generates a random n...

| description | The invention relates to an embedded software anti-cloning method. The method comprises the steps that the FPGA calculates a first authentication secret key according to a preset root secret key and a DNA serial number; when the embedded system initiates authentication, the FPGA generates a random number, obtains first authentication information according to the random number and the first authentication key, and sends the random number to the processor; the processor receives the random number sent by the FPGA, calculates according to the random number and a preset second authentication key to obtain second authentication information, and sends the second authentication information to the FPGA; and the FPGA receives the second authentication information, performs matching authentication according to the first authentication information and the second authentication information to obtain a matching result, and judges whether the service processing function needs to be subjected to function limitation accordin |
