Method and computer for protecting computer security based on bios password

Abstract

The invention discloses a method for protecting computer security based on a BIOS password and a computer adopting the method, comprising the following steps: a storage step, writing the BIOS password in the BIOS chip in the background, setting parameters of the password checking option in the BIOS, and storing the password in the BIOS chip. The parameters are stored in the CMOS chip; the computer startup step, after the power supply voltage is stable, the CPU jumps; the block code startup step, the BIOS starts the block code; the self-test step, the device performs self-test, after the self-test passes, the control display pops up to enter the password dialog box; password capturing step, computer captures the password typed from the keyboard; password caching step, stores the captured password in the keyboard register; password comparison step, CPU reads out the input password, and compares it with the BIOS password ;Security execution steps, perform corresponding operations according to the result of password comparison. The method of the invention has high security performance, the password cannot be deciphered, and can effectively protect the setting security of the computer and the security of data in the computer.

Description

technical field [0001] The invention relates to a method for protecting computer security, in particular to a computer protection method using BIOS encryption, which belongs to the technical field of computers. Background technique [0002] With the development of science and technology and the advancement of the network, computer applications have expanded to various fields, but the security problems of local computers have also become increasingly serious. At first, people set up login accounts under the system to protect the security of local computers, but this method exists. Many loopholes have many cracking methods. Therefore, the system login account method cannot guarantee the security of the computer very reliably. [0003] In addition, there are some computer security protection methods, such as software encryption. However, the current software encryption methods have more or less defects. For example, serial number authentication is used, which is easier to be tr...
