Embodiment Construction

[0012] see figure 1 The encryption system of the computer motherboard of the present invention includes a central processing unit 1, a BIOS memory 2, an encryption processor 3 and a reset control circuit 4. BIOS memory 2 and encryption processor 3 are all connected with central processing unit 1 by bus; Reset control circuit 4 is connected with encryption processor 3 and central processing unit 1, and encryption processor 3 sends three kinds of signals C1, C2, C3 to reset The control circuit 4 is used to force the circuit to generate a reset signal to the central processing unit 1, so that the main board of the computer is restarted.

[0013] In the computer motherboard, BIOS is the basic software that the computer motherboard must have to realize its hardware functions. Each computer motherboard product has a matching and customized BIOS. The function of the computer motherboard is closely combined with the BIOS software. The BIOS carrier is usually It is a dedicated BIOS me...

Abstract

The invention relates to an encryption system and its encryption method of the computer main board, which is composed of the CPU, the BIOS memory, the encryption processor and the reset controlling circuit. The BIOS memory and the encryption processor are connected to the CPU via the bus. The password check-up program is added to the BIOS start-up procedure stored in the BIOS memory. By this means, the encryption processing to the main board is implemented when the computer's main board starts up. The reset controlling circuit is connected to the encryption processor and the CPU. The encryption processor transfers signals to the reset controlling circuit and force the circuit to generate the reset signal to the CPU to reset the computer's main board. The invention effectively encrypts the main board of the computer and the embedded system.

Description

【Technical field】 [0001] The invention relates to a computer mainboard, in particular to an encryption system and an encryption method for a computer mainboard. 【Background technique】 [0002] At present, most computer motherboards do not have encryption, so some criminals take the opportunity to imitate and embezzle other people's computer motherboards and their embedded application systems, thereby causing serious losses to product development stakeholders; in addition, even if there is encryption, it is often only embedded applications. System developers implement encryption in application software, so replacing hardware cannot effectively control imitation. 【Content of invention】 [0003] In order to overcome the disadvantage that existing computer motherboards are easy to be imitated and embezzled, the present invention provides an encryption system and an encryption method for computer motherboards, so as to prevent embezzlement of computer motherboards and applicati...
