Embodiment Construction

[0053] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0054] Such as figure 1 As shown, a safe state switching system is applicable to a computer system, and the computer system includes:

[0055] processing unit 1, namely the processor of the computer system;

[0056]The first storage unit 2, that is, the memory of the computer system, is connected to the processing unit 1, and is used to store data or instructions for processing by the processing unit 1;

[0057] The processing unit 1 also receives instructions input from the external network and performs corresponding processing.

[0058] In a preferred embodiment of the present invention, the processing unit 1 works through a first operating system.

[0059] Therefore, in a preferred embodiment of the present invention, the above-mentioned safe state switching system specifically includes: ...

Abstract

The invention discloses a safe state switching system and switching method, and belongs to the technical field of computer system safety. The system comprises an input unit, a state switching unit, a detecting unit and a safe processing unit, the state switching unit is connected with the input unit, the detecting unit is connected between a storage unit and a processing unit, and is connected with the state switching unit, and the safe processing unit is respectively connected with a communication unit, the storage unit and the state switching unit. The method comprises the steps that a sate instruction is acquired; the safe state of a computer system is set according to the state instruction; whether data sent to the processing unit are normal or not is detected according to the level of the safe state, and then the data judged to be abnormal are intercepted; the safe processing unit is started according to the level of the safe state and replaces the processing unit to work. According to the technical scheme, the system and method have the advantages that the abnormal data in the Internet are intercepted, the safety of the computer system is guaranteed, and normal running of a computer is not influenced.

Description

technical field [0001] The invention relates to the technical field of computer system security, in particular to a security state switching system and switching method. Background technique [0002] With the advent of the information age, users can theoretically access any computer on the network through the Internet, regardless of the physical location of the computer being accessed. Therefore, in theory, a computer on the network can be accessed through The Internet accesses control commands and data sent by other computers. [0003] The processor chips currently used in computers do not rule out the possibility of being artificially set up as a "safety back door", that is, some special instructions may be set in the processor chip, and these special instructions are activated by calling external instructions, thereby destroying the normal operation of the computer process, such as issuing an "automatic shutdown" command to the computer system, etc. These "safety backdoo...
