Embodiment Construction

[0041] Figure 5 It shows the in-depth concept of the protection system that can be provided by the system and method for ensuring the original running of the program according to the embodiment of the present invention. Such as Figure 5 As shown, according to the present invention, it is possible to establish a protection system deeper than the system hardware level. More specifically, the security protection system provided by the present invention is a level that hackers / viruses cannot go deep into, because hackers / viruses can only exist in The operating system cannot go deep into the protection system lower than the system hardware level, thus ensuring that the protection system will never be damaged.

[0042] As is well known, any runnable program consists of three parts: program command, which represents a line of commands; program sequence, which represents a set of program commands; and data, including input, output and program accompanying data.

Abstract

A method for ensuring program to be operated in original state includes storing program entity and reference program frame separately in and in storages of protective system and operation system in advance, operating two said systems independently and fetching program entity from said operation system to comparator as well as fetching reference program frame from said protective system to comparator, comparing program frame of program entity itself with reference program frame in comparator then confirming that program is distorted if the two are not the same or otherwise confirming that program is normal.

Description

technical field [0001] The present invention relates generally to the fields of computer architecture and secure computing. More specifically, the present invention relates to a system and method for ensuring the original state of the program, wherein the protection system exists independently from the operating system and monitors the operation of the operating system in real time, so as to ensure the original state of the program without interfering with the operation normal operation of the system. Background technique [0002] Computational security and secure computing have always been a major topic in the computer field. With the increasing popularity of the Internet, more and more computers are connected to the network, forming an increasingly large computing system. In theory, any connection between two computers is natural, or it is feasible to go from one computer to another. In reality, even a computer without Internet access cannot exist in isolation, for exam...
