Software running method of high-safety information system

Abstract

The invention provides a software running method of a high-safety information system. The high-safety information system comprises an information processing component, a control component and a storage component, wherein the control component comprises a hardware switch; at least one control signal wire for the information processing component to carry out the writing operation on the second storage component is connected with the second storage component through the control component; when the hardware is positioned in a first state, the control component cuts off the connection between the control signal and the second storage component through the signal wire; when the control component is in a second state, the control component maintains the connection between the control signal and the second storage component through the signal wire and runs the software step of judging whether the hardware switch is in the first state or not and operating the hardware switch to be in the first state when the hardware switch is not in the first state; and the information processing component reads partial or all codes of the software program from the second storage component, stores the partial or all codes in a storage space of the information processing component and runs the partial or all codes.

Description

technical field [0001] The invention relates to a software running method of a high-safety information system, in particular to a software running method of a safe information system for preventing computer virus intrusion and computer hacker attack by adopting a method of controlling a hardware connection signal between a processor and a storage body. Background technique [0002] Explanation of terminology: The computer virus or virus mentioned in the present invention all have the same meaning, including adopting the clear definition in the "Computer Information System Security Protection Regulations of the People's Republic of China", that is, a computer virus "refers to compiling or inserting A set of computer instructions or program codes that destroy computer functions or data, affect the use of computers and are capable of self-replication”; also include those inserted into information systems other than computers that destroy information system functions or data, aff...
