Abstract

The invention discloses a firmware starting method based on PIN code authorization. The method comprises the following steps that 1, a TCM security card is used in a computer integrated with the TCM security card; step 2, starting up and electrifying, and detecting the TCM security card by the security firmware; 3, when it is detected that the state of the security card is normal and the firmwareflag bit is not started, the screen pops up a prompt box to prompt a user to input a PIN code; 4, the user inputs the PIN code in a manual input mode or in a mode of reading the file from the storagedevice; step 5, the firmware sends the received PIN code to the TCM for verification; and step 6, after the verification is passed, the firmware starts the mark position and continues to start the system, and if the verification is not passed, prompts re-input and prompts the remaining input times, and shuts down when the maximum fault-tolerant times are exceeded. The method can prevent TCM resources from being exposed in an unsafe environment, prevent the computer from being started in the unsafe environment and use the computer resources, and is better in safety.

Description

technical field [0001] The invention relates to the technical field of computer security, in particular to a firmware startup method based on PIN code authorization. Background technique [0002] Firmware is an important basic software in a computer system, and is generally solidified and stored in a flash chip. The motherboard, graphics card, network card, and hard disk of the computer all have firmware. Although they have different functions, they all use and drive hardware in essence. The most important firmware in the computer is called BIOS (Basic Input / Output System), which is used to initialize the motherboard hardware, manage hardware resources, and boot the operating system. It is a bridge connecting the basic computer hardware and system software. [0003] The development of BIOS has gone through two eras. The BIOS of the first era is called legacy BIOS, and the BIOS of the second era is called UEFI (Unified Extensible Firmware Interface). Legacy BIOS was born in...
