Method for energizing and starting high-security information system

Abstract

The invention provides a method for energizing and starting a high-security information system. The high-security information system comprises an information processing component, a controlling component and a second storing component. The controlling component comprises a hardware switch; at least one control signal line of the information processing component for carrying out the write operation and / or the data updating operation and / or the data modifying operation and / or the data adding operation and / or the data deleting operation and / or the data refreshing operation is connected with the second storing component through the controlling component; when the hardware switch is in the first state, the controlling component cuts off the connection of the control signal and the signal line of the second storing component; and when the hardware switch is in the second state, the controlling component keeps the connection of the control signal and the signal line of the second storing component. The method for energizing and starting the high-security information system comprises the following steps: operating the hardware switch to make the hardware switch in the first state; energizing the high-security information system; cutting off the connection of the control signal and the signal line of the second storing component by the controlling component; and implementing the energizing initializing program by the information processing component.

Description

technical field [0001] The invention relates to a power-on start-up method of a high-safety information system, in particular to a power-on start-up method of a safe information system that prevents computer virus invasion and computer hacker attack by adopting a method for controlling a hardware connection signal between a processor and a storage body.
