A Rapid Virus Immune File Distribution Method Based on Enhanced Index Tree

Abstract

In order to solve the more and more serious problems of network virus spreading, network virus infection and network virus attacks, the invention provides an enhanced index tree-based quick virus immunizing document distribution method capable of being adopted to improve the network virus resisting capacity of each host node in an Internet-based open network computing environment. The method comprises the following steps: firstly, according to discovered network viruses, manufacturing virus immunizing documents of which each comprises a patch program and a virus library updating program by an anti-virus central node set by an authoritative antivirus organization; and then quickly distributing the virus immunizing documents based on a new enhanced index tree through resource sharing and communication channels of a network so that each node in the network can quickly acquire the virus immunizing documents to be patched and update a virus library to be immunized as soon as possible, thereby quickly enhancing the new virus resisting capacity of most of the nodes in the network, effectively solving the problems of virus spreading, virus infection and virus attacks in the Internet environment and reducing the degree of the harm of the viruses to a network system.

Description

technical field [0001] The present invention is a fast virus immune file distribution method based on enhanced index tree, which can be used to improve the resistance ability of each host node to network viruses in an Internet-based open network computing environment. This technology belongs to the cross technical application field of information security, information system, computer network and computer software. Background technique [0002] Computer virus originally refers to a computer instruction or program code inserted into a computer program that destroys computer functions or data, affects computer use and can replicate itself. It is divided into viruses that infect executable files and those that run in the background for malicious control and destruction Viruses, worms, and script viruses. [0003] Since the birth of the Internet, it has been welcomed by a large number of users. Every day, thousands of Internet users around the world communicate, exchange resour...

Problems solved by technology

[0006] Traditional anti-virus software basically needs to find and confirm a virus first, and then prevent it. There is no effective way to deal with the deformation of various viruses, and it cannot effectively prevent viruses that incorporate hacker technology.
