Embodiment Construction
[0023] Further description will be given below in conjunction with the accompanying drawings and the embodiment of the hardware authorization system and method of the present invention.
[0024] The hardware authorization system device of the present invention is as figure 1 As shown, including network remote server (1), local computer (2) and hardware processor HMI (3), network remote server (1) and local computer (2) are connected through a network link, local computer (2) and hardware The processor HMI (3) is connected via a USB cable.
[0025] The network remote server (1) stores the encryption algorithm and the hardware startup code binary file, and can calculate a key for the hardware processor HMI (3) according to the MAC address of the hardware processor HMI (3) to be authorized uploaded by the local computer (2) , and pass back the key and bootcode binary to the local computer (2).
[0026] The local computer (2) can read the unique MAC address of the CPU of the har...

The invention provides a hardware authorization system and method for performing encryption authorization on a hardware processor by adopting an encryption algorithm and a hardware processor separation method through a remote server. The system comprises a network remote server, a local computer and a hardware processor; and the system stores an encryption program and a decryption program in the network remote server and the to-be authorized hardware processor respectively, so that an encryption process and a decryption process are located in two different places, the network remote server, by using the local computer, conducts encryption authorization for the hardware processor, and when the hardware processor is started, the check can be passed by enabling unique MAC address and key to be in one-to-one correspondence with a unique hardware boot code. Unless the encryption and decryption algorithms can be simultaneously cracked and the unique key and hardware boot code are simultaneously obtained, the hardware processor subjected to encryption authorization by the system cannot be cracked.
Description
technical field [0001] The invention relates to a hardware authorization system and method, which authorizes hardware through a remote server, and belongs to the technical field of computers. Background technique [0002] Hardware encryption technology is an information encryption technology that binds encrypted information to hardware processors. Generally, AES128-bit or 256-bit hardware data encryption technology is used to encrypt product hardware processors, which can prevent violent cracking, password guessing, data recovery, etc. Function. [0003] At present, known hardware encryption technologies all utilize encryption programs stored in a memory inside a hardware processor to perform hardware authorization encryption. Since the encryption program itself is stored on the hardware processor, once someone cracks the memory, the encryption program loses its protection. This authorized encryption method is relatively difficult to crack, and cannot effectively protect t...
