The invention discloses a method for guiding a terminal equipment operation system based on a USB controller, and belongs to the technical field of terminal equipment information security. The method is characterized in that on the premise that the hardware, the structure and the BIOS module of terminal equipment are not changed, and only an MBR of a magnetic disk, a PBR of a guiding sector and BootLoader are modified, identity information of a user, the USB controller and the terminal equipment are bound, and after user identity verification and credibility verification of the guiding sector of the magnetic disk are passed, the control right of guiding the terminal equipment operation system is transferred to all appointed memory regions, including the MBR, appointed by the decrypted system MBR, so that the operation system is guided. Self-guiding security of the terminal equipment is considered, security of the user identity is considered, a data recovery mechanism is provided for the terminal equipment, and the guiding sector is prevented from being tempered. The method supports a domestic code algorithm, is particularly suitable for the application scene where the user carries a portable computer for working in travel, and improves the working security for the user.
Description
technical field [0001] The present invention relates to the field of information security, in particular to a method for using a USB controller to guide the operating system of a terminal device. An operating system is installed on the terminal device, and the operating system is guided through a USB controller, so that the terminal device cannot be started independently. Background technique [0002] With the development of information technology, the problem of information security is becoming more and more serious. At present, some important information systems still use a large number of desktop computers and portable computers as terminal equipment. Due to the oversimplification of the security mechanism of the hardware structure of the terminal equipment and the lack of security design of the relevant modules, there are many security problems in the information system. To solve the security problems of the information system, we must start with the security of the term...
