Embodiment Construction
[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] see figure 1 , is a schematic structural diagram of a system for a hardware anti-copying board according to an embodiment of the present invention. The system for the anti-copying board of the hardware of the embodiment of the present invention comprises hardware product main controller and integrated circuit chip, and hardware product main controller is used for calculating MAC (Media Access Control, address) by authentication algorithm according to the key of random data and storage data, and transmit the random data to the integrated circuit chip; the integrated circuit chip is used to c...

The invention belongs to the technical field of copyright protection of a hardware product and particularly relates to a system and a method for a hardware anti-copying board. The system for the hardware anti-copying board comprises a hardware product main controller and an integrated circuit chip, wherein the hardware product main controller is used for calculating MAC (Media Access Control) data according to random data and a stored secret key and transmitting the random data to the integrated circuit chip; the integrated circuit chip is used for calculating another MAC data according to the random data transmitted by the hardware product main controller and transmitting back the MAC data to the hardware product main controller; the hardware product main controller judges whether two pieces of MAC data are equal and if the two pieces of MAC data are equal, authentication is passed and the hardware product main controller continuously executes; if the two pieces of MAC data are not equal, authentication is failed and the hardware product main controller resets the system or enters the endless loop. According to the invention, cloning is prevented in a bidirectional authentication manner and the safety class of the hardware product is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of copyright protection of hardware products, and in particular relates to a system and method for a hardware anti-copying board. Background technique [0002] A set of hardware products consists of hardware and software codes solidified in hardware memory. Using reverse technology can easily clone corresponding hardware products, which will damage the interests of original product manufacturers, suppliers and design companies, and is not conducive to the healthy development of the industry. In the prior art, the common copying and cloning methods are as follows: [0003] 1) Use non-volatile memory such as board-level Flash to store the running code; this memory is solidified and can still be saved when the power is off; remove the memory of the original product and put it on a specific card reader, which can be read Read all the data stored in the memory, burn the read data into the cloned hardware single...
